Deuteronomy

And when the Lord thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:

And the Lord gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the Lord delivered all their enemies into their hand.

But of the cities of these people, which the Lord thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth:

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:

Thou shalt make no covenant with them, nor with their gods.
