"And the daughters of the sister," for if she is his sister's daughter, or his sister's son's daughter, or his sister's daughter's daughter, and those below them, she is a sister's daughter. "And your mothers who nursed you and your sisters through nursing," whatever is forbidden by lineage is also forbidden by nursing; thus, his mother through nursing is not lawful for him, nor are any maternal ancestors above her. Likewise, his sister through nursing, his paternal aunt through nursing, the paternal aunt of his father through nursing, the paternal aunt of his mother through nursing, and those above them are not lawful. The same applies to a maternal aunt through nursing, the maternal aunt of his father, the maternal aunt of his mother, and those above them. Similarly, his brother's daughter through nursing, his brother's son's daughter through nursing, his brother's daughter's daughter through nursing, and those below them are not lawful, nor are his sister's daughter through nursing, his sister's son's daughter through nursing, his sister's daughter's daughter through nursing, and those below them.

If a woman nurses a boy, that boy may not marry any of her daughters; neither those born with him, nor before that, nor after it, though his brothers may marry her children if they wish. Likewise, if she nurses a girl, none of her children may marry that girl, neither those born before her nursing nor after it, though her brothers may marry her children if they wish.

"And the mothers of your wives," the mother of a man's wife is not lawful for him, nor are her mothers. "And your step-daughters who are under your guardianship, born of your wives unto whom you have entered; but if you have not entered unto them, there is no sin upon you." So, if a man marries a woman and divorces her before having entered unto her, or she dies before he enters unto her, he may marry her daughter if he wishes. However, if he has entered unto her, he may not marry her daughter, nor her daughter's daughter, nor those below them.
