Deuteronomy 7:2-4

Complete Jewish Bible

² When he does this, when Adonai your God hands them over ahead of you, and you defeat them, you are to destroy them completely! Do not make any covenant with them. Show them no mercy. ³ Don’t intermarry with them — don’t give your daughter to his son, and don’t take his daughter for your son. ⁴ For he will turn your children away from following me in order to serve other gods. If this happens, the anger of Adonai will flare up against you, and he will quickly destroy you.
