Mishneh Torah, Forbidden Intercourse
If a Jewish person sleeps with a non-Jew in the way of married people, they receive biblically ordained lashes, as it says “You shall not intermarry with them: do not give your daughter to their sons or take their daughters for your sons.” (Deuteronomy 7:3) The same law is true concerning the seven nations of the land of Canaan and all other nations. This is also explained by Ezra, “We will not give our daughters in marriage to the peoples of the land, or take their daughters for our sons.” (Nehemiah 10:31)
