Deuteronomy 7:2-4

Amplified Bible, Classic Edition

² And when the Lord your God gives them over to you and you smite them, then you must utterly destroy them. You shall make no covenant with them, or show mercy to them.

³ You shall not make marriages with them; your daughter you shall not give to his son nor shall you take his daughter for your son,

⁴ For they will turn away your sons from following Me, that they may serve other gods; so will the anger of the Lord be kindled against you and He will destroy you quickly.
