Deuteronomy 7:3-5

International Standard Version

³ You are not to intermarry with them. You are not to give your daughters to their sons nor take their daughters for your sons, ⁴ because they will turn your children from me to serve other gods so that the Lord’s anger blazes against you and swiftly destroys you by fire. ⁵ This is what you are to do to them: tear down their altars, break their pillars, cut down their ritual pillars, and burn their carved idols in fire,
