Mishnah Makkot
And these are liable to be flogged:One who had relations with his sister, or his father's sister, or his mother's sister, or his wife's sister, or his brother's wife, or his father's brother's wife, or a menstruant; A high priest who marries a widow, an ordinary priest who marries a divorcee or a halutzah; An Israelite who marries a mamzereth or natinah, or an Israelite woman who is married to a mamzer or a natin. In the case of a [woman who is both] a divorcee and a widow [a high priest] is liable on two counts. But in the case of a [woman who is both] a divorcee and a halutzah, an ordinary priest is liable only on one count.
Mishnah Sotah
A betrothed woman and a shomeret yavam do not drink [the bitter waters] and do not receive their ketubah, as it is said, “When a wife, being under her husband, goes astray” (Numbers 5:29), this excludes a betrothed woman and a shomeret yavam. A widow who had married a high priest, a divorced woman or a halutzah who had married an ordinary priest, a mamzeret or a netinah who had married an Israelite, and the daughter of an Israelite who had married a mamzer or a natin do not drink [the bitter waters] and do not receive their ketubah.
Mishnah Yevamot
An Ammonite and a Moabite are forbidden [to enter into the congregation of the Lord] and their prohibition is for ever. However, their women are permitted at once. An Egyptian and an Edomite are forbidden only until the third generation, whether they are males or females. Rabbi Shimon permits their women immediately. Said Rabbi Shimon: This is a kal vehomer: if where the males are forbidden for all time the females are permitted immediately, where the males are forbidden only until the third generation how much more should the females be permitted immediately. They said to him: If this is a halakhah, we shall accept it; but if it is only a logical reference, there is a refutation. He replied: This is not so, I am in fact saying a halakhah. Mamzerim and nethinim are forbidden, and their prohibition is forever, whether they be males or females.
