Deuteronomy 7:1-10

When Jehovah thy God shall bring thee into the land whither thou goest to possess it, and shall cast out many nations before thee, the Hittite, and the Girgashite, and the Amorite, and the Canaanite, and the Perizzite, and the Hivite, and the Jebusite, seven nations greater and mightier than thou; and when Jehovah thy God shall deliver them up before thee, and thou shalt smite them; then thou shalt utterly destroy them: thou shalt make no covenant with them, nor show mercy unto them; neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. For he will turn away thy son from following me, that they may serve other gods: so will the anger of Jehovah be kindled against you, and he will destroy thee quickly. But thus shall ye deal with them: ye shall break down their altars, and dash in pieces their pillars, and hew down their Asherim, and burn their graven images with fire. For thou art a holy people unto Jehovah thy God: Jehovah thy God hath chosen thee to be a people for his own possession, above all peoples that are upon the face of the earth. Jehovah did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all peoples: but because Jehovah loveth you, and because he would keep the oath which he sware unto your fathers, hath Jehovah brought you out with a mighty hand, and redeemed you out of the house of bondage, from the hand of Pharaoh king of Egypt. Know therefore that Jehovah thy God, he is God, the faithful God, who keepeth covenant and lovingkindness with them that love him and keep his commandments to a thousand generations, and repayeth them that hate him to their face, to destroy them: he will not be slack to him that hateth him, he will repay him to his face.
