Deuteronomy 7:1-2
The Dispossession of Nonvassals
7:1 When the Lord your God brings you to the land that you are going to occupy and forces out many nations before you – Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites, seven nations more numerous and powerful than you –
7:2 and he delivers them over to you and you attack them, you must utterly annihilate them. Make no treaty with them and show them no mercy!
Deuteronomy 7:24
7:24 He will hand over their kings to you and you will erase their very names from memory.
Nobody will be able to resist you until you destroy them.
