Deuteronomy 20:15 Meaning and Commentary

Deuteronomy 20:15

15 This is how you are to treat all the cities that are far away from you and are not among the cities of these nations.
16 However, you must not let any living thing survive among the cities of these people the Lord your God is giving you as an inheritance.
17 You must completely destroy them-the Hittite, Amorite, Canaanite, Perizzite, Hivite, and Jebusite-as the Lord your God has commanded you,
