Deuteronomy 7:2-4

Good News Translation

² When the Lord your God places these people in your power and you defeat them, you must put them all to death. Do not make an alliance with them or show them any mercy. ³ Do not marry any of them, and do not let your children marry any of them, ⁴ because then they would lead your children away from the Lord to worship other gods. If that happens, the Lord will be angry with you and destroy you at once.
