When it comes to the enemy God gives clear instructions. Destroy the enemy.
Read: Deuteronomy 7:1-2
“When the Lord your God brings you into the land which you go to possess, and has cast out many nations before you, the Hittites and the Girgashites and the Amorites and the Canaanites and the Perizzites and the Hivites and the Jebusites, seven nations greater and mightier than you, 2 and when the Lord your God delivers them over to you, you shall conquer them and utterly destroy them. You shall make no covenant with them nor show mercy to them.
