128 Eduyot 5/2-5

(2) Rabbi Yose says: There are six things about which Beit Shammai was more lenient and Beit Hillel was more stringent. Poultry can be put on the [same] table [as] cheese, but cannot be eaten [with it], such are the words of Beit Shammai. And Beit Hillel says: It cannot be put [on the same table], and it cannot be eaten [with it]. One can take terumah [the portion given to the priest] from olives on behalf of oil, and from grapes on behalf of wine, such are the words of Beit Shammai. And Beit Hillel says: One does not take terumah [on behalf of oil and wine from their fruits of origin]. One who sows [seeds] within four cubits of a vineyard, Beit Shammai says: One row [of the vineyard that is closest to the area where one sowed the seeds] is rendered prohibited. And Beit Hillel says: Two rows are rendered prohibited. A water-flour mixture: Beit Shammai exempt [from the law of challah, where a portion of dough is set aside for the priest], and Beit Hillel obligate [it]. One may ritually immerse oneself in a waterfall, such are the words of Beit Shammai. And Beit Hillel says: One may not immerse oneself [there]. A convert who converts on the eve of Passover [which requires the eating of the Paschal lamb that night, only by those who are ritually pure], Beit Shammai says: He may immerse and eat the Paschal lamb that night. And Beit Hillel says: One who separates from the uncircumcised is like he who separates from the grave [i.e. he must wait seven days before he can immerse in a ritual bath, so he cannot eat the Paschal lamb that night].

(3) Rabbi Yishmael says: Three items about which Beit Shammai are more lenient and Beit Hillel are more stringent. The book of Ecclesiastes does not make [a person's] hands ritually impure, such are the words of Beit Shammai. And Beit Hillel says: It [does] make the hands ritually impure. The waters of the [red heifer, biblically referred to as the waters of the] sin-offering, which have fulfilled their duty [by having been sprayed on a person who had come in contact with a dead person]: Beit Shammai declares ritually pure, and Beit Hillel declares ritually impure. Black cumin: Beit Shammai declares ritually pure [as they do not consider it a food], and Beit Hillel declares ritually impure [as they do consider it a food]. And the same [considerations about the black cumin's status as food apply] to [their positions on] tithing [for the black cumin].

(4) Rabbi Eliezer says: Two things about which Beit Shammai was more lenient and Beit Hillel was more stringent. The blood of a woman who [had waited the week or two weeks after] giving birth [to a boy or a girl, respectively] who had yet to ritually immerse, Beit Shammai says: It [imparts impurity when it is wet] like her spit and her urine. And Beit Hillel says: It imparts impurity whether [it is] wet or dry. And they agree that if that woman after childbirth was a zavah [a woman with an abnormal genital discharge], [her discharge] would impart impurity whether wet or dry.

(5) Four brothers, two of whom are married to two sisters, and those two brothers married to the sisters die, the [two surviving brothers] must perform chalitzah [the ceremony of release, after which a Levirate marriage is no longer required] and not [enter into] Levirate marriages. If they went and entered [into Levirate marriages anyway], they must leave [the marriages]. Rabbi Eliezer said in the name of Beit Shammai: [The Levirate marriages] stay upheld. And Beit Hillel says: They must leave [the marriages].
