2,155. Sennacherib Mixed the Nations

Hilchos Issurei Biah 12:24

David and his court passed the enactment against the Nesinim because he saw that they had a cruel streak in them since they insisted on killing and hanging the seven sons of King Saul, who had been chosen by God, and they refused to have mercy on them.

Hilchos Issurei Biah 12:25

When Sancheriv, the king of Assyria, took power, he mixed all the nations together and exiled them from their homelands. The result is that the Egyptians who currently live in Egypt are actually descended from other nations. This also applies to the Edomites in Edom. Since the four prohibited nations were mixed among all the other nations – who are permitted after conversion – all converts are therefore permitted. When any of them separates from his or her nation through conversion, we assume that they separated from the majority. Therefore, nowadays, whenever a non-Jew converts, whether he or she is Edomite, Egyptian, Amonite, Moabite, Ethiopian or any other nationality, they’re immediately permitted to join the general Jewish marriage pool.
