Yevamos 9:6-10:1

Yevamos 9:6

If the daughter of a kohein married a Yisroel, she may not eat terumah. If he died and she had a son from him, she may not resume eating terumah. If she subsequently marries a Levi, she may eat maaser. If he died and she had a son from him, she may continue eating maaser. If she subsequently marries a kohein, she may eat terumah. If he died and she had a son from him, she may continue eating terumah. If her son from the kohein dies, she may no longer eat terumah (but she may eat maaser). If her son from the Levi dies, she may no longer eat maaser. If her son from the Yisroel dies, she “goes back to her father’s house” (i.e., re-assumes the status “daughter of a kohein”) and may one again eat terumah, as per Leviticus 22:13.

Yevamos 10:1

Let’s say that a woman’s husband went overseas and witnesses from there came and reported that he died, so she remarried but her husband subsequently turned up alive. In such a case, she must divorce each husband, she requires a get from each husband, and she does not receive the value of her kesubah or other financial benefits from either husband. If she received these benefits from either husband, she must repay them. If she has a child with either husband, it is a mamzer (the product of an adulterous relationship). If either husband is a kohein, he may not allow himself to be rendered ritually unclean to bury her. Neither husband is entitled to an item that she may find or to profits she might earn, and neither may annul her vows. If she was the daughter of a Yisroel, she may no longer marry a kohein; if the daughter of a Levi, she may not eat maaser and if the daughter of a kohein, she may not eat terumah. Neither husband’s sons inherit the value of her kesubah. If the husbands died, the brothers of each perform chalitzah and not yibum. Rabbi Yosi says that her kesubah is a lien on the first husband’s property. Rabbi Elazar says the first husband is entitled to an item that she finds and to profits that she earns, and he may annul her vows. Rabbi Shimon says that the first husband’s brother may perform yibum or chalitzah and doing either one exempts her co-wife, and if she returns to the first husband, their offspring is not a mamzer. Rabbi Shimon also says that if she married based on the witnesses’ testimony, without permission of the court, she may return to her first husband.
