Netilat Yadayim: Why Jews Wash Their Hands

Before eating bread, on waking up, after leaving the bathroom: observant Jews pour water over their hands, two or three times, with a precise gesture, sometimes with a blessing, and often in silence. This is not a gesture of hygiene, since one can have perfectly clean hands and still have to do it. Where does this practice come from, what does the Torah say, what do the Talmud, Maimonides and the Shulchan Aruch say, and what does it mean today? This article answers by distinguishing law (halakha), moral and mystical readings, and what history and archaeology allow us to say about it.

The short answer

Netilat yadayim (in Hebrew, “the taking of water for the hands”) is a rite of purification of the hands instituted by the Sages, who tied it to the Torah. It is practiced before eating bread (and after the meal, under the name mayim acharonim, “last waters”), on waking, after certain acts and before prayer, by pouring water from a vessel (kli) over each hand up to the wrist. Its origin lies in the service of the kohanim (priests) in the sanctuary, who had to wash their hands and feet before officiating (Shemot [Exodus] 30:17-21); the Sages extended to every Jewish table this requirement of purity, which survived the destruction of the Temple. Alongside the rule, the masters have read in it a way of turning the table into an altar and the morning into a new beginning; we shall always distinguish the two.

What are we talking about? The different handwashings

First, a confusion must be cleared up: there is not one handwashing but several, which do not all have the same origin or the same rule.

Washing before bread (netilat yadayim lisudah or lechem): the best known. One washes one’s hands, says a blessing, then recites Hamotzi over the bread. This is the central rule (Shulchan Aruch, Orach Chaim 158:1).
Washing after the meal (mayim acharonim): one rinses the fingertips before Birkat Hamazon, the grace after meals. Without a blessing (Rambam, Hilkhot Berakhot 6:2; Shulchan Aruch, Orach Chaim 181).
Morning washing: on waking, before praying, one pours water over one’s hands, with a blessing (Shulchan Aruch, Orach Chaim 4:1-2).
Washings after certain acts: after going to the bathroom, after touching certain parts of the body, after a visit to the cemetery (Shulchan Aruch, Orach Chaim 4:18; Yoreh De’ah 376:4).
Washings tied to a particular moment: that of the Pesach seder (urchatz, without a blessing), and that of the kohanim before blessing the people, which the Levites assist (Shulchan Aruch, Orach Chaim 473:6; 128:6).

The word netila does not mean exactly “washing”: the rite consists less in rubbing than in pouring water from a vessel over the hands, as we shall see.

At the origins: the priests’ basin

Nowhere does the Torah prescribe that every Israelite wash his hands before eating. What the written Torah knows is the washing of the kohanim, the priests, before the service. When G-d commands the construction of the Tabernacle, He also asks for a copper basin, the kiyor, placed between the Tent of Meeting and the altar:

“Aharon and his sons shall wash their hands and their feet from it. When they enter the Tent of Meeting, they shall wash with water, so that they not die; or when they approach the altar to minister, to burn a fire-offering to the L-rd.”

(Shemot 30:19-20) — וְרָחֲצוּ אַהֲרֹן וּבָנָיו מִמֶּנּוּ אֶת־יְדֵיהֶם וְאֶת־רַגְלֵיהֶם׃ בְּבֹאָם אֶל־אֹהֶל מוֹעֵד יִרְחֲצוּ־מַיִם וְלֹא יָמֻתוּ אוֹ בְגִשְׁתָּם אֶל־הַמִּזְבֵּחַ לְשָׁרֵת לְהַקְטִיר אִשֶּׁה לַיהֹוָה׃

The text returns at the end of the book: Moshe and the priests wash “as the L-rd had commanded” (Shemot 40:30-32). What is at stake is clear, and grave: “so that they not die”. Contact with the sacred requires preparation, and the preparation begins with the hands, the instruments of all action.

The Psalmist takes up this image for every person: “One who has clean hands and a pure heart” (Tehilim [Psalms] 24:4); “I will wash my hands in innocence and circle Your altar, L-rd” (Tehilim 26:6). These are images, not laws, which the Talmud will use as support.

The Talmud draws a striking image from it (Berakhot 15a). Rabbi Yochanan teaches that one who, in the morning, relieves himself, washes his hands, puts on tefillin, recites the Shema and prays accomplishes something equivalent to the service of the altar; Rava proposes, on the same verse, another reading: it is as if he had immersed himself entirely, for the verse says “I will wash” and not “I will wash my hands”.

“Rabbi Yochanan said: whoever relieves himself, washes his hands, puts on tefillin, recites the Shema and prays, Scripture considers him as one who has built an altar and offered a sacrifice on it, for it is written: ‘I will wash my hands in innocence and circle Your altar, L-rd.'”

(Berakhot 15a) — כָּל הַנִּפְנֶה, וְנוֹטֵל יָדָיו, וּמַנִּיחַ תְּפִילִּין, וְקוֹרֵא קְרִיאַת שְׁמַע, וּמִתְפַּלֵּל — מַעֲלֶה עָלָיו הַכָּתוּב כְּאִלּוּ בָּנָה מִזְבֵּחַ וְהִקְרִיב עָלָיו קׇרְבָּן, דִּכְתִיב: ״אֶרְחַץ בְּנִקָּיוֹן כַּפָּי וַאֲסוֹבְבָה אֶת מִזְבַּחֲךָ ה׳״.

The essential distinction is this: in the Torah, handwashing is a requirement of the service in the sanctuary. For the ordinary Israelite, it becomes an obligation by decision of the Sages, who wanted to make everyone’s table a place comparable to the one where the priest eats the holy portion, the terumah.

An institution of the Sages: Shlomo, Hillel and Shammai, Rabbi Elazar ben Arach

Who instituted the washing?

The Talmud does not give a single answer, but a story in layers. Here are the three names it puts forward.

King Shlomo (Solomon). “Rav Yehuda said in the name of Shmuel: when Shlomo instituted the eruvin (the pooling of courtyards for Shabbat) and netilat yadayim, a heavenly voice went out and said: ‘My son, if your heart is wise, My heart too will rejoice’ (Mishlei 23:15)” (Eruvin 21b; the same tradition is taken up in Shabbat 14b-15a). The Talmud thus gives an honorable framework to the measure: even Shlomo, the wisest of kings, protected the Torah with rabbinic “fences”.

Hillel and Shammai. The Talmud (Shabbat 14b) reports a series of decrees of impurity: Yose ben Yoezer and Yose ben Yochanan on the land of the nations and on glass, Shimon ben Shetach on metal utensils, and “Shammai and Hillel decreed impurity upon the hands”. The hands are declared impure in a rabbinic manner: anyone whose hands have not been washed renders impure the terumah he touches. This is the logic of the kohanim: whoever eats terumah must have washed his hands. The Mishna, moreover, shows the two schools, Beit Shammai and Beit Hillel, debating the details of the rite at the table: whether one should wash the hands before or after preparing the cup of wine, where to place the napkin, and so on (Mishna Berakhot 8:2-4).

The Talmud (Chullin 106a) speaks of a third moment: the one when the obligation was extended from kodesh (the sacred) to chullin, ordinary food. It gives two reasons for this. The first has to do with proximity to terumah (mipnei serech terumah): if all Israel washes the hands to eat, the kohanim will not get into the habit of eating terumah without having washed. The second: a mitzvah. Which one? Two opinions:

“Abaye said: it is the mitzvah of listening to the words of the Sages. Rava said: it is the mitzvah of listening to the words of Rabbi Elazar ben Arach, for it is written: ‘and he has not rinsed his hands in water’ (Vayikra [Leviticus] 15:11). Rabbi Elazar ben Arach said: from here the Sages found support, in the Torah, for netilat yadayim.”

(Chullin 106a) — רָבָא אָמַר: מִצְוָה לִשְׁמוֹעַ דִּבְרֵי רַבִּי אֶלְעָזָר בֶּן עֲרָךְ, דִּכְתִיב: ״וְכֹל אֲשֶׁר יִגַּע בּוֹ הַזָּב וְיָדָיו לֹא שָׁטַף בַּמָּיִם״. אָמַר רַבִּי אֶלְעָזָר בֶּן עֲרָךְ: מִכָּאן סָמְכוּ חֲכָמִים לִנְטִילַת יָדַיִם מִן הַתּוֹרָה.

Here we see how halakha works: the washing is rabbinic (from the words of the Sages), but it rests, through a reading, on a verse of the Torah, and it is protected by the Torah’s general commandment to listen to the masters (Devarim [Deuteronomy] 17:11, which the Rambam cites in this connection).

Why a blessing?

The Rambam answers that the blessing “who has sanctified us with His commandments and commanded us concerning netilat yadayim” is justified because the Torah itself commanded us to listen to the Sages: “according to the teaching they will teach you” (Devarim 17:11; Hilkhot Berakhot 6:2).

Rabbi Akiva and the prison wall

The Talmud illustrates the seriousness the Sages attach to this rule with a famous story. Rabbi Akiva is in prison, and Rabbi Yehoshua Hagarsi brings him every day a measured ration of water. One day, the guard pours out half of it, suspecting that the water will be used to undermine the walls. When Rabbi Yehoshua arrives, Rabbi Akiva asks him for water to wash his hands before eating. The other replies: there is not enough to drink, and you want to wash your hands with it? The answer fits in one line:

“What shall I do? Those who [transgress the words of the Sages] are liable to death. Better that I die by my own death than transgress the opinion of my colleagues.”

(Eruvin 21b) — אָמַר לוֹ: תֵּן לִי מַיִם שֶׁאֶטּוֹל יָדַי, אָמַר לוֹ: לִשְׁתּוֹת אֵין מַגִּיעִין, לִיטּוֹל יָדֶיךָ מַגִּיעִין?! אָמַר לוֹ: מָה אֶעֱשֶׂה שֶׁחַיָּיבִים עֲלֵיהֶן מִיתָה? מוּטָב אָמוּת מִיתַת עַצְמִי, וְלֹא אֶעֱבוֹר עַל דַּעַת חֲבֵירַי!

The Talmud continues: he tasted nothing until water had been brought for his hands, and the Sages said: “If in his old age and in prison he is like this, how much more so in his youth and outside prison!” (Eruvin 21b). Akiva’s sentence connects to that of Rava just before it on the same page, according to which anyone who transgresses the words of the Sages incurs death: it is a hyperbole of teaching, not a penalty applied by a court. The episode shows that netilat yadayim is no subtlety, and that one does not exempt oneself from a rule one helped establish, even when everything invites it.

Why wash the hands? Several levels of answer

Over the centuries the masters have proposed several explanations, which do not exclude one another. Distinguishing them helps avoid confusing the law with its interpretation.

The level of the law: purity, not cleanliness

The fundamental point, which the Rambam underlines from the opening of his law: one must wash the hands “even if they are not dirty and one knows of no impurity on them”:

“Every person who eats bread over which one says Hamotzi must wash his hands at the beginning and at the end. Even if it is ordinary bread, even if his hands are not dirty and he knows of no impurity on them, he shall not eat until he has washed both hands.”

(Rambam, Hilkhot Berakhot 6:1)

The commentators explain the hands as “active” (askaniot): they touch constantly, and one may have touched an impure object without knowing it (a phrase linked to the Rambam’s commentary on the Mishna, Tohorot 7:8; see also Mishnah Berurah 158:1). In other words, netilat yadayim is not hygiene: it does not depend on the state of cleanliness of the skin.

The practical consequence is important: whatever, in matters of ritual immersion, forms a barrier between the skin and the water (the chatzitza) forms a barrier here too. The Shulchan Aruch recalls it: “whatever forms a barrier in immersion forms a barrier in netilat yadayim”, with a tolerance for small quantities, since one is not bothered by them (Orach Chaim 161:1). If you have read our article on the mikveh, you will recognize the logic.

The level of the Talmud: respect for the table

The Talmud reports harsh words, to be read in their context. In Sotah 4b, Rav Avira teaches that “whoever eats bread without netilat yadayim is as if he had consorted with a prostitute”, based on the verse “for on account of a prostitute one is brought to a loaf of bread” (Mishlei 6:26); and Rabbi Zerika says in the name of Rabbi Elazar:

“Whoever treats netilat yadayim lightly is uprooted from the world.”

(Sotah 4b) — כׇּל הַמְּזַלְזֵל בִּנְטִילַת יָדַיִם נֶעֱקָר מִן הָעוֹלָם.

These sentences are derashot, homiletic readings: through hyperbole, they express the seriousness the Sages attached to a rule that one might think trivial. Halakha, for its part, speaks of a mandatory rabbinic institution (Rambam, Hilkhot Berakhot 6:1-2).

The Talmud adds that “one who eats bread without wiping his hands is as if he were eating impure bread” (Rabbi Abbahu, citing Yechezkel [Ezekiel] 4:13), and reports the custom of Rav Chisda, who wanted abundance:

“Rav Chisda said: I wash my hands with a full handful of water, and I was given in return a full handful of good.”

(Shabbat 62b) — רַב חִסְדָּא: אֲנָא מְשַׁאי מְלֵא חָפְנַי מַיָּא וִיהַבוּ לִי מְלֵא חָפְנַי טֵיבוּתָא.

The Shulchan Aruch draws the rule from it: it is better to pour abundantly (Orach Chaim 158:10).

The level of the ethical reading: the hand that acts

In the Letter of Aristeas, a Judeo-Hellenistic text from Egypt, the translators of the Torah into Greek wash their hands in the sea before praying. When asked why, they answer that it is “a sign that they have done no wrong, for every action is accomplished by the hands” (Letter of Aristeas 305-306). This passage, earlier than the Mishna, attests to a moral reading of the rite, close to the psalm’s phrase “one who has clean hands” (Tehilim 24:4): the hand is the organ of action, and to wash it is to remember that one answers for what one does.

This is not the halakhic explanation (the rabbinic purity of the hands), but an ethical reading that grafted itself onto it very early. The Mishnah Berurah, for its part, sums up the halakha in two reasons: proximity to terumah, and “cleanliness and holiness”, the latter supported by the verse “You shall sanctify yourselves and you shall be holy” (Mishnah Berurah 158:1).

The level of holiness: a new morning

For the morning washing, the Mishnah Berurah (Orach Chaim 4:1) reports two reasons, which are also two ways of understanding the rite. The first is that of the Rosh (Rabbenu Asher, 13th-14th century): the hands are “active” and may, during the night, have touched without one’s knowing it an impure part of the body. The second is that of the Rashba: in the morning, “we become a new creature”, as the verse says “they are new every morning, great is Your faithfulness” (Eicha 3:23), and one thanks G-d for having created us to serve Him.

“The Rashba writes: since in the morning, after sleep, we become like a new creature… [it was instituted] to sanctify ourselves with His holiness and to pour water over our hands from a vessel, like the kohen who sanctifies his hands at the basin before his service.”

(Mishnah Berurah, Orach Chaim 4:1, citing the Rashba) — והרשב”א כתב לפי שבשחר אחר השינה אנו נעשים כבריה חדשה … להתקדש בקדושתו וליטול ידינו מן הכלי ככהן שמקדש ידיו מן הכיור קודם עבודתו.

In halakha, both are retained: “we follow both reasons, stringently” (ibid.).

The mystical level: the “evil spirit” of the night

The Shulchan Aruch adds a motive that belongs to the mystical tradition:

“One should take care to pour water over them three times to remove the evil spirit that rests upon them.”

(Shulchan Aruch, Orach Chaim 4:2) — ידקדק לערות עליהם מים ג’ פעמים להעביר רוח רעה ששורה עליהן:

How should this be understood? The Mishnah Berurah specifies that this motive is not enough to ground a blessing: the Sages would not have instituted a blessing “for the evil spirit alone”; that is why the other reasons mentioned above are needed (Mishnah Berurah 4:8). The masters therefore distinguish the law (purity and sanctification) from the mystical layer, which each person receives according to his tradition. The custom of pouring three times is explained by this motive.

The same Shulchan Aruch lists the situations in which one must wash the hands (getting out of bed, leaving the bathroom or the baths, cutting one’s nails, taking off one’s shoes…) and promises the one who neglects it, if he is a scholar, that his learning will be lost (Orach Chaim 4:18): a homiletic warning, which says above all how much these gestures were valued.

How one washes: netilat yadayim in practice

The practice rests on a few principles, found in the Mishna, the Talmud, the Rambam and the Shulchan Aruch. We give the broad outlines; for any specific question, consult a rabbi.

A vessel, a certain quantity of water

One pours the water from a vessel (kli): “one pours water over the hands only from a vessel” (Mishna Yadayim 1:2), and almost all kinds of vessels are valid:

“One pours water over the hands from any vessels, even vessels of dung, vessels of stone, vessels of earth.”

(Mishna Yadayim 1:2) — בְּכָל הַכֵּלִים נוֹתְנִין לַיָּדַיִם, אֲפִלּוּ בִכְלֵי גְלָלִים, בִּכְלֵי אֲבָנִים, בִּכְלֵי אֲדָמָה.

The vessel must be able to hold at least a revi’it (a quarter of a log) and be intact (Shulchan Aruch, Orach Chaim 159:1). The Mishna specifies how much water is needed: a revi’it for one person or two, more if several wash together (Yadayim 1:1). Today the revi’it is estimated at about 86 ml according to some (Shiurei Torah) and 150 ml according to the Chazon Ish. What matters above all is that the water be poured by the force of a person, and not flow of its own accord (Chullin 107a).

How far? Nothing must form a screen

One washes the hand up to the wrist, according to the Rambam, adopted by the Shulchan Aruch (Hilkhot Berakhot 6:4; Orach Chaim 161:4), whereas the Rosh is satisfied with the joint of the fingers. The Mishna says that the hands become impure and pure “up to the perek” (Yadayim 2:3). Nothing must form a barrier, as with the mikveh (Orach Chaim 161:1).

The order of the gestures

The Shulchan Aruch describes the classic form: one first pours a little water to remove what is dirty, then a second time, and finally a third time to purify the water remaining on the hands; if the hands are clean and one has plenty of water, one may pour a whole revi’it at once. One rubs the hands against each other (Orach Chaim 162:2). The custom of the great majority of communities is thus to pour two or three times over each hand.

After the washing, one raises the hands (Sotah 4b) and dries them (“one who eats without wiping his hands is like one who eats impure bread”, Sotah 4b). The rule is that one must not interrupt between the washing and the blessing Hamotzi: “There are those who say that one need not take care not to interrupt between the washing and Hamotzi, and those who say that one must take care, and it is good to take care” (Orach Chaim 166:1).

When to say the blessing?

The Shulchan Aruch lays down the logical rule, then notes the custom:

“One should bless before washing, for every mitzvah is blessed over before it is performed. But the custom is not to bless until after washing, because sometimes the hands are not clean.”

(Shulchan Aruch, Orach Chaim 158:11) — מברך קודם נטילה שכל המצות מברך עליה’ עובר לעשייתן ונהגו שלא לברך עד אחר נטילה משום דפעמים שאין ידיו נקיות

The Rema (Ashkenazic custom) adds that one may bless even before drying, since drying is part of the mitzvah. In Ashkenazic practice, then, one blesses after washing, before drying (Mishnah Berurah 158:41); among many Sephardim, one follows the description of the Shulchan Aruch instead. For the morning washing, the Mishnah Berurah specifies that one blesses “immediately after the washing, without waiting for the drying” (Orach Chaim 4:2).

When does one wash? The situations of life

Before bread

One washes before eating bread over which Hamotzi is said, that is, real bread, or foods that come close to it if they serve as the basis of the meal (Shulchan Aruch, Orach Chaim 158:1). For pastry (pat haba’a bekisnin) or small rolls not taken as a meal, one does not wash.

The Rambam adds that one also washes the hands for any food dipped in a liquid (Hilkhot Berakhot 6:1); the current custom, however, is to say the blessing only for bread. Fruit, for its part, requires no washing: “one who washes his hands to eat fruit is among the arrogant” (Rambam, Hilkhot Berakhot 6:3; Chullin 106a).

After the meal: mayim acharonim

The washing at the end of the meal follows another logic, more prosaic. The Talmud gives the reason: “Why did the Sages say that the last waters are an obligation? Because there is a Sodomite salt that makes one blind” (Chullin 105b). In other words: by passing the hand over the eyes after eating salted bread, one risked injury. The Rambam classes it under the heading of danger (sakana) and denies it any blessing (Hilkhot Berakhot 6:2-3).

“Rav Yehuda, son of Rabbi Chiya, said: why was it said that the last waters are an obligation? Because there is a Sodomite salt that blinds the eyes.”

(Chullin 105b) — אָמַר רַב יְהוּדָה בְּרֵיהּ דְּרַבִּי חִיָּיא: מִפְּנֵי מָה אָמְרוּ מַיִם אַחֲרוֹנִים חוֹבָה? שֶׁמֶּלַח סְדוֹמִית יֵשׁ, שֶׁמְּסַמֵּא אֶת הָעֵינַיִם.

The Shulchan Aruch states: “The last waters are an obligation” (Orach Chaim 181:1), then adds: “There are those who are not accustomed to wash their hands with the last waters” (181:10). The custom therefore varies: some communities and some families observe it scrupulously, others do not. A delicate person (istenis) who is accustomed to washing the hands after the meal must in any case do so before Birkat Hamazon (181:10).

In the morning

On waking, one washes the hands before praying and says the blessing al netilat yadayim (Orach Chaim 4:1-2); some add Asher yatzar (“who formed man with wisdom”), even if one has not gone to the bathroom, according to the Rema (Orach Chaim 4:1). The blessing Asher yatzar itself comes from the Talmud (Berakhot 60b): “on leaving, one says: ‘Blessed are You… who formed man with wisdom and created in him orifices and cavities…'”; the blessing Elohai neshama, right nearby, is said “on waking” (ibid.). The same passage gives the wording of the blessing on handwashing (Berakhot 60b).

A Talmudic facility: in the morning, one may wash the hands with the condition that the washing is valid for the whole day (Chullin 107a; Shulchan Aruch, Orach Chaim 164:1). The Rema specifies that this condition does not apply to the washing tied to food.

Other moments

Before prayer: the Talmud includes handwashing in the morning order, before tefillin, the Shema and prayer (Berakhot 15a), and the Rambam asks that one wash the hands before prayer (Hilkhot Berakhot 6:2; Hilkhot Tefila 4:2-3).
After a cemetery: the custom is to wash the hands on leaving the cemetery (Yoreh De’ah 376:4); see our article on mourning in Judaism.
At the Pesach seder: one washes the hands before the karpas (urchatz), without a blessing (Orach Chaim 473:6); see What is Pesach and how does the seder unfold?.
The kohanim before blessing the people: they wash their hands again up to the wrist; a Levite pours the water over their hands (Orach Chaim 128:6); see Who are the kohanim, the Levites and the Israelites?.
On Yom Kippur: one washes the hands in the morning with the blessing, but only up to the end of the finger joints, not seeking the pleasure of the water but only to remove the evil spirit (Shulchan Aruch, Orach Chaim 613:2).

A little history and archaeology

A rite known before the Mishna. The Letter of Aristeas, a Judeo-Hellenistic text from Egypt generally dated to the 2nd century BCE, describes the translators of the Torah into Greek who, “according to the custom of all the Jews, washed their hands in the sea and prayed” before translating (§ 305-306). Whatever part of this account is legend, it attests that a Jewish author in Hellenistic Egypt held this gesture to be customary and justified it by a symbol of innocence.

In the Gospels. The Gospel of Mark reports that some Pharisees are astonished to see Jesus’ disciples eat “with defiled hands, that is, unwashed”, and specifies that “the Pharisees and all the Jews do not eat without washing their hands, holding to the tradition of the elders” (Mark 7:1-5). The text is by an author outside the rabbinic world, but it confirms that washing before meals was already, in the 1st century, a characteristic practice of the Pharisees, whose heirs the Sages of the Talmud consider themselves.

Stone vessels. The Mishna permits pouring water for the hands from a stone vessel (Yadayim 1:2), and archaeologists have unearthed in Jerusalem and Judea, for the Second Temple period (from the early 1st century BCE until the destruction of the Temple in 70 CE), workshops producing stone vessels, a material the tradition held not susceptible to impurity. See for example Yitzhak Magen and Levana Tsfania, The Stone Vessel Industry in the Second Temple Period, 2002. This is an indication of the concern for purity of the time, with no established link to netilat yadayim in particular.

Differences of custom between communities

The basic halakha is common, but customs vary.

Time of the blessing: Sephardim usually follow the Shulchan Aruch (after the first rinse), Ashkenazim the Rema (after the washing, before drying; Orach Chaim 158:11).
Number of pourings: the almost universal custom is to pour two or three times (Shulchan Aruch, Orach Chaim 162:2), whereas certain Yemenite groups, following the letter of the Rambam, are said to pour only once, according to Rabbi Yosef Kafach (notes to Hilkhot Berakhot 6:4).
Last waters: observed by some, not by others, already since the Shulchan Aruch (Orach Chaim 181:10).

Common misconceptions about netilat yadayim

“It’s hygiene”

No. The Rambam provides for washing even if the hands are clean (Hilkhot Berakhot 6:1), and the Shulchan Aruch, on the contrary, assumes that one first removes any dirt before purifying (Orach Chaim 162:2). Hygiene is a side benefit; the law aims at purity and the sanctification of the meal. See also our article on the mikveh, which rests on the same distinction.

“It’s a rite of guilt, as if the hands were dirty”

Not that either. In the Torah, the hands are “dirty” only from the standpoint of ritual purity, not of morality. The Sages speak of “active” hands (askaniot), that is, constantly busy, whose purity cannot be guaranteed. No judgment on the person.

“One only washes the hands before bread”

No: there is also the morning, after the bathroom, before prayer, after a cemetery, and the last water after the meal. Only the washing before bread is tied to Hamotzi.

“One can wash the hands at the tap, like everyone”

Halakha requires pouring the water from a vessel (Yadayim 1:2; Orach Chaim 159:1). Special situations (tap, hospital, travel) are for a rabbi.

Frequently asked questions about handwashing

Why does the washing have a blessing, if it is not a mitzvah of the Torah?

Because the Torah asks us to listen to the Sages (Devarim 17:11), obeying their decree is itself a mitzvah, and one blesses over it (Rambam, Hilkhot Berakhot 6:2).

Must one wash the hands before eating fruit?

No. The Talmud and the Rambam specify that one does not wash the hands for fruit, and that one who does so is considered arrogant (Chullin 106a; Hilkhot Berakhot 6:3).

Why the hands before prayer?

Because, according to the Rashba, one sanctifies oneself like the kohen at the basin before his service (Mishnah Berurah 4:1), and because the Talmud places the washing in the morning order before prayer (Berakhot 15a; Rambam, Hilkhot Tefila 4:2-3).

Why does one pour the water two or three times?

The Shulchan Aruch describes a first pouring to remove dirt or what forms a barrier, a second, then a third “to purify the water that is on the hands” (Orach Chaim 162:2). For the morning washing, it also asks that one pour three times, to drive away the “evil spirit” (Orach Chaim 4:2).

Does the washing still have meaning without the Temple?

Yes. The Mishnah Berurah explains that the rule was not abolished when the kohanim ceased to eat terumah: it keeps its two reasons, preparation for purity “when the Temple is rebuilt”, and “cleanliness and holiness” (Mishnah Berurah 158:1).

Why Do Jews Wash Their Hands (Netilat Yadayim)?
