Deuteronomy 20:17 in the King James Version
But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the LORD thy God hath commanded thee:
Context
16 But of the cities of these peoples that the LORD your God gives you for an inheritance, you shall save alive nothing that breathes;
17 but you shall utterly destroy them: the Hittite, the Amorite, the Canaanite, the Perizzite, the Hivite, and the Jebusite, as the LORD your God has commanded you;
18 that they not teach you to follow all their abominations, which they have done for their gods; so would you sin against the LORD your God.
