In several places in the Jewish Bible, there are relations which appear to be intermarriages - for example, King David is described as marrying the daughter of the king of Geshur, Christine Hayes compares the Deuteronomic and Ezran viewpoints on intermarriage, and discusses in terms of ritual impurity and the fear of profaning the seed of Israel.
First and foremost, Hayes holds that the fear of profaning the seed of Israel was the underlying rationale for the ban in exogamous marriage, rather than the ritual impurity of Gentiles in general.
Although we refer to ourselves as G-d's chosen people, we do not believe that G-d chose the Jews because of any inherent superiority.
According to the Talmud (Avodah Zarah 2b), G-d offered the Torah to all the nations of the earth, and the Jews were the only ones who accepted it.
Interfaith marriage in Judaism (also called mixed marriage or intermarriage) was historically looked upon with very strong disfavour by Jewish leaders, and it remains a controversial issue amongst them today.“For many years, I told myself (and others) that I was going to the nearby Catholic college so I could meet a nice Catholic boy and get married,” Richards recalls.But when she met Levy—who is Jewish—the two quickly became friends and eventually started dating.The principle is essentially a general one, and the deuteronomic explanation doesn't clarify why it singles out the Canaanites in particular; one of the Talmudic writers took it to forbid all intermarriage with non-Jewish nations.with a Midianite woman (not from the seven Canaanite nations); this took place at a time when foreign (Moabite) women were inducing the Jews to perform idolatry.
