Deuteronomy 7:2-4

The Voice

² The Eternal your God will put them in your power. You must crush them; destroy them completely! Don’t make any treaties with them, and don’t show them any mercy. ³ Above all, don’t intermarry with them! Don’t marry your daughters to any of their sons, and don’t marry your sons to any of their daughters.

Eternal One: ⁴ This would cause your enemies to turn your children away from Me to worship other gods.

Moses: If you did worship other gods, the Eternal would become furious with you and destroy you in an instant!
