Deuteronomy 7:6-12

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. Thou shalt therefore keep the commandment, and the statutes, and the ordinances, which I command thee this day, to do them. And it shall come to pass, because ye hearken to these ordinances, and keep and do them, that Jehovah thy God will keep with thee the covenant and the lovingkindness which he sware unto thy fathers
