Netilat Ya'Dayim

Rav Naḥman bar Yitzḥak said ... I know a baraita, as Rav Yehuda said that Rav said, and some say that it was taught in a baraita: It is stated: “And you shall sanctify yourselves, and you shall be holy, for holy am I, the Lord your God” (Leviticus 20:26). With regard to this verse, the Sages said: And you shall sanctify yourselves, these are the first waters with which one washes his hands before the meal; and you shall be holy, these are the final waters; for holy, this is oil which one spreads on his hands; am I, the Lord your God, this is the Grace after Meals blessing.

(1) Anyone who eats bread, which we bless ha-motzi [who brings out]" over, requires washing of the hands at the beginning and end [of the meal]. And [this is the case] even though the bread is ordinary [i.e. not consecrated] and even though his hands are not dirty, and he does not know of any ritual impurity regarding them, he does not eat until he washes his two hands. And so too any matter of dipping in liquids - it requires washing of the hands at the beginning.

(5) One ritually washes one's hands for chullin [unsanctified food], ma'aser [tithed food] and for terumah [food tithed as the priest's gift]. For kodesh [portions of offerings eaten by the priests] one must immerse [in a mikveh]. And for chattat [water of purification] if one's hands are [ritually] impure, one's body is [ritually] impure.

(1) When one comes to eat bread that we bless on it "HaMotzi", one should wash their hands, even if one does not know that they have any impurity, one should bless: "al n'tilat yadayim"/"regarding washing of hands". But bread that we do not bless "HaMotzi" on it, for example, little rolls, (explanation: satorti in another language), or bread that comes as dumplings (explanation: bread that is made with sugar, almonds, and nuts), and one does not establish a meal with them, one does not need to wash their hands.
