Mishnah Yevamot 11

¹A man is permitted to marry [the relative] of a woman [whom he has] raped or seduced. He who rapes or seduces [a relative] of his married wife, is guilty. A man may marry a woman whom his father has raped or seduced or a woman whom his son has raped or seduced. Rabbi Yehudah forbids [marriage] with a woman whom one’s father has raped or seduced. ²The sons of a female convert who converted with her do not perform halitzah or yibbum, even if the one was not conceived in holiness but was born in holiness, and the other was both conceived and born in holiness. So also [is the law] where the sons of a female slave were freed together with her. ³If the children of five women were mixed up and, when these mixed up children grew up, they took wives and then died, four perform halitzah for one [of the widows] and one contracts with her yibbum. [Then] he and three [brothers] perform halitzah to [another one of the widows] and one has with her yibbum. Thus every one [of the widows] has halitzah four times and yibbum once. ⁴If the child of a woman was mixed up with the child of her daughter-in-law and the mixed-up children grew up and married women and then died, the [other] sons of the daughter-in-law perform halitzah but may not contract yibbum, for it is uncertain whether she is the wife of his brother or the wife of his father’s brother. The [other] sons of the older woman either perform halitzah or yibbum, since the only doubt is whether she is the wife of his brother or the wife of his brother’s son. If the not-mixed-up sons died then [with respect to the widows of the sons of the older woman] the mixed-up sons perform halitzah and may not have yibbum, since it is uncertain whether she is the wife of his brother or the wife of his father’s brother; [With respect to the widows] of the sons of the daughter-in-law one performs halitzah and the other [may] have yibbum. ⁵If the child of a priest’s wife was mixed-up with the child of her female slave, behold both may eat terumah and [together] they receive one share at the threshing-floor. They may not defile themselves for the dead nor may they marry any women whether these are eligible [for marriage with a priest] or ineligible. If when they grew up, the mixed-up children freed one another they may marry women who are eligible for marriage with a priest and they may not defile themselves for the dead. If they defiled themselves, they do not receive the penalty of forty lashes. They may not eat terumah, but if they did eat they need not pay compensation either for the principal or [the additional] fifth. They are not to receive a share at the threshing-floor, but they may sell [their own] terumah and the proceeds are theirs. They receive no share in the holy things of the temple, and no holy things are given to them but others do not take their holy things from them. They are exempt from [giving to any priest] the shoulder, the cheeks and the maw, while the firstling of either of them should remain in the pasture until it contracts a blemish. The restrictions relating to priests and the restrictions relating to Israelites are both imposed upon them. ⁶If a woman did not wait three months after [separation from] her husband, and married again and gave birth [to a son], and it is unknown whether it is a nine-months child by the first husband or a seven-months child by the second, if she had other sons by the first husband and other sons by the second, these must perform halitzah but may not contract yibbum. So too he, with their widows performs halitzah but may not contract yibbum. If he had brothers by the first and also brothers by the second, but not by the same mother, he may either perform halitzah or contract yibbum, But as for them, one performs halitzah and the other may [then] contract yibbum. ⁷If one of [the two husbands] was an Israelite and the other a priest: He may only marry a woman who is eligible to marry a priest. He may not defile himself for the dead, but if he did defile himself he does not suffer the penalty of forty stripes. He may not eat terumah, but if he did eat he need not pay compensation either for the principal or [for the additional] fifth. He does not receive a share at the threshing-floor, but he may sell [his own] terumah and the profits are his. He receives no share in the holy things of the temple, no holy things are given to him, but he is not deprived of his own. He is exempt from [giving to any priest] the shoulder, the cheeks and the maw, while his firstling must remain in the pasture until it contracts a blemish. The restrictions relating to priests and the restrictions relating to Israelites are imposed upon him. If the two [husbands] were priests: He must be an onen mourner for them and they must be onenim mourners for him, but he may not defile himself for them, nor may they defile themselves for him. He may not inherit from them, but they may inherit from him. He is exempt if he strikes or curses the one or the other. He goes up [to serve] in the Temple watch of the one as well as of the other, but he does not receive a share [in the offerings]. If both served in the same watch, he receives a single portion.
