תּלמוד אויף ויקרא 15:18

There¹⁶Mishnah Niddah 5:1. In the Babli, Niddah 41b, the names between R. Joḥanan and R. Simeon ben Laqish are switched., we have stated: “All women become impure in the outer cavity¹⁷The impurity of menstrual blood is not dependent on the blood being visible outside her body; it is enough to be close to the vagina..” What is the outer cavity? Rebbi Joḥanan said, up to the place which is seen when girls sit down to urinate. Rebbi Simeon ben Laqish said to him, but in all impurities particular to her, she becomes impure only up to the place of teeth¹⁸Impurities cannot be transmitted inside body cavities. For food, this means that impure food thrown into one’s mouth will not result in any impurity of the eater if it touches the walls of the mouth behind the tetth (except carcass meat). By analogy, anything happening in the womb of a woman inside of a place which can be considered corresponding to the teeth in the mouth cannot have any influence on her status of purity. The Yerushalmi to Niddah 5 is lost; in the Babli, Rav Jehudah defined the “teeth” as the place reached by the male organ during intercourse. That place is defined as being open to the outer world since Lev. 15:18 decrees that semen causes impurity in the body of the woman.. Rebbi Zakkai stated: Up to the place of teeth, and from between the teeth to the inside. Rebbi Yose ben Rebbi Abun in the name of Samuel: The entire genitals are called “outer cavity”¹⁹This statement has no parallel in the Babli..

“The deaf-and-dumb disables.” Did not Rebbi Ḥiyya state: “The wife of the deaf-and-dumb or the insane immerses herself from her husband’s bosom and eats⁹⁸In Tosephta 9:4: “The sane daughter of a Cohen married to an insane Israel …” Since marriages of the deaf-and-dumb or the insane are not valid, the woman does not lose her priestly status. She has to immerse herself after intercourse with her husband (Lev. 15:18) but is not disabled from eating heave. This contradicts the Mishnah.”? Rebbi Abba Mari and Rebbi Mattaniah, one said, a disqualified deaf-and-dumb⁹⁹A person whose intercourse would disable the woman even if he were hearing., the other said, a deaf-and-dumb levir¹⁰⁰He disqualifies as levir, whose standing is not different from a hearing man; cf. Chapter 6, Note 35..

This supports what Rebbi Ḥiyya stated⁹⁸In Tosephta 9:4: “The sane daughter of a Cohen married to an insane Israel …” Since marriages of the deaf-and-dumb or the insane are not valid, the woman does not lose her priestly status. She has to immerse herself after intercourse with her husband (Lev. 15:18) but is not disabled from eating heave. This contradicts the Mishnah.: The wife of the deaf-and-dumb or the insane immerses herself from her husband’s bosom and eats, against Rebbi Eleazar, since Rebbi Eleazar said, also if an unmarried man had intercourse with an unmarried woman not for the purpose of marriage it is copulation of harlotry¹⁰⁵Cf. Chapter 6, Note 108. The woman would be disabled from marrying into the priesthood. Quoted in Babli 61b, 59b; Sanhedrin 51a, Temurah 30a..
