Deuteronômio 23:4 Referências da Mishná: Mishnah Yadayim, Mishnah Yevamot & Mishnah Gittin

On that day Judah, an Ammonite convert, came and stood before them in the house of study. He said to them: Do I have the right to enter into the assembly? Rabban Gamaliel said to him: you are forbidden. Rabbi Joshua said to him: you are permitted. Rabban Gamaliel said to him: the verse says, "An Ammonite or a Moabite shall not enter into the assembly of the Lord: even to the tenth generation" (Deuteronomy 23:4). R. Joshua said to him: But are the Ammonites and Moabites still in their own territory? Sanheriv, the king of Assyria, has long since come up and mingled all the nations, as it is said: "In that I have removed the bounds of the peoples, and have robbed their treasures, and have brought down as one mighty the inhabitants" (Isaiah 10:1. Rabban Gamaliel said to him: the verse says, "But afterward I will bring back the captivity of the children of Ammon," (Jeremiah 49:6) they have already returned. Rabbi Joshua said to him: [another] verse says, "I will return the captivity of my people Israel and Judah" (Jeremiah 30:3). Yet they have not yet returned. So they permitted him to enter the assembly.

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.

[If he said,] “You are permitted to any man but my father, your father, my brother, your brother, a slave, a Gentile, or anyone to whom she is incapable of being betrothed,” the get is valid. [If he said,] “You are permitted to anyone but (supposing she was a widow) a high priest, or, (supposing she was a divorcee or a halutzah) an ordinary priest, or, (supposing she was a mamzeret or a netinah) a regular Israelite, or (supposing she was an Israelite) a mamzer or a natin, or anyone who is capable of betrothing her even in transgression, the get is invalid.
