Intermarriage and Interdating?

When the Lord your God brings you to the land that you are about to enter and possess, and He dislodges many nations before you -- the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites, seven nations much larger than you -- and the Lord your God delivers them to you and you defeat them, you must doom them to destruction: grant them no terms and give them no quarter. You shall not intermarry with them: do not give your daughter to their sons or take their daughters for your sons. For they will turn your children away from Me to worship other gods, and the Lord’s anger will blaze forth against you and He will promptly wipe you out.

You must not make a covenant with the inhabitants of the land, for they will lust after their gods and sacrifice to their gods, and invite you, and you will eat of their sacrifices. And when you take wives from among their daughters for your sons, their daughters will lust after their gods and will cause your sons to lust after their gods.

And the rest of the people, the priests, the Levites, the gatekeepers, the singers, the temple servants, and all who separated themselves from the peoples of the lands to [follow] the Teaching of God, their wives, sons and daughters, all who know enough to understand, join with their noble brothers, and take an oath with sanctions to follow the Teaching of God, given through Moses the servant of God, and to observe carefully all the commandments of the Lord our Lord, His rules and laws. Namely: We will not give our daughters in marriage to the peoples of the land, or take their daughters for our sons...

Rava interjects, is the reason for the prohibition “do not intermarry with them” a matter of sanctity? Rather, it is out of fear that the intermarried couple will have a child whowill worship idolatry. This prohibition against intermarriage applies only againstnon-Jews, but if they convert, they are allowed for marriage.

How do we know that marriage with a non-Jew is not viable? The verse says “do not intermarry with them,” we see that marriage to a non-Jew is not viable. Rabbi Yochanan says in the name of Rabbi Simon ben Yochai, the verse says “for he will turn your children away from Me” -- A child who comes from a Jewish woman is called “your child”; A child who comes from a non-Jewish woman is not called “your child” but “her child.” Ravina says, we conclude from here that the son of your daughter who comes from a non-Jewish father is called “your son.”
