Deuteronomy 20:17-18

NHEB(i) 17 but you shall utterly destroy them: the Hethite, and the Amorite, the Canaanite, and the Perizzite, and the Hivite, and the Jebusite; as the LORD your God has commanded you; 18 that they not teach you to do after all their abominations, which they have done to their gods; so would you sin against the LORD your God.
