신명기 23:1의 관련

Rabbi Yehuda forbids [marriage] with [a woman who was] raped by his father or seduced by his father, as it is said (Lev. 18:7-8), "You shall not uncover the nakedness of your father, etc.," and further on it says (Deut. 22:13), "A man shall not take his father's wife, and he he shall not uncover his father's garment." And it says (Deut. 22:19), "She is to remain his wife, etc." § A [female] convert whose sons converted along with her: They (i.e., her deceased husband's brothers) do not perform chalitzah or yibbum. [If her sons'] conception was not in sanctity, and their birth was not in sanctity they do not perform chaltizah or yibbum, and they are not liable on account of [the prohibition against marriage to] "the wife of one's brother." [If her sons'] conception was not in sanctity, but their birth was in sanctity, they may perform either chalitzah or yibbum, but they are liable on account of "the wife of one's brother." [If] their conception was in sanctity and their birth was in sanctity, behold, they are like an Israelite in every respect.
