Deuteronomy 7:1-6 NKJV
“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, 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. Nor shall you make marriages with them. You shall not give your daughter to their son, nor take their daughter for your son. For they will turn your sons away from following Me, to serve other gods; so the anger of the LORD will be aroused against you and destroy you suddenly. But thus you shall deal with them: you shall destroy their altars, and break down their sacred pillars, and cut down their wooden images, and burn their carved images with fire.
“For you are a holy people to the LORD your God; the LORD your God has chosen you to be a people for Himself, a special treasure above all the peoples on the face of the earth.
