Yevamos 13:10-11

Yevamos 13:10

Let’s say that a man who is married to one woman with congenital deafness and to another woman with all her senses dies. His brother performs yibum with the woman who has all her senses, and then he does so again with the woman who has congenital deafness, or another brother then has relations with the woman who has congenital deafness. In such a case, the first man is not disqualified from remaining married to the woman with all her senses. If the deceased’s brother performs yibum with the woman who has congenital deafness, and then he does so again with the woman who has all her senses, or another brother then has relations with the woman who has all her senses, it disqualifies the first man from remaining married to the woman who has congenital deafness.

Yevamos 13:11

If a man is married to an adult and a minor and he dies, if his brother performs yibum with the adult, and then he does so again with the minor, or another brother then has relations with the minor, it does not disqualify the first man from remaining married to the adult. If the deceased’s brother performs yibum with the minor, and then he does so again with the adult, or another brother then has relations with the adult, it does disqualify the first man from remaining married to the minor. Rabbi Elazar says that the minor is coached to refuse yibum.
