Deuteronomy 20:16-18

JuliaSmith(i) 16 Only of the cities of these peoples which Jehovah thy God gave to thee an inheritance, thou shalt not preserve alive and breathing: 17 For destroying, thou shalt destroy them, the Hittite, and the Amorite, the Canaanite, and the Perizzite, the Hivite, and the Jebusite, as Jehovah thy God commanded thee: 18 So that they shall not teach you to do according to all their abominations to their gods; and ye sinned to Jehovah your God.
