Deuteronómio 23:9 Referencias de la Mishná: Mishnah Yevamot

An ordinary priest shall not marry a woman incapable of procreation, unless he already has a wife or children. Rabbi Judah said: even though he has a wife and children he shall not marry a woman incapable of procreation, since she is a zonah, as mentioned in the Torah. But the Sages said: the term zonah implies only a female convert, freed slavewoman and one who has been subjected to illicit intercourse.

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.
