Deuteronomy 7:7-11King James Version (KJV)
7 The Lord 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 people:
8 But because the Lord loved you, and because he would keep the oath which he had sworn unto your fathers, hath the Lord brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt.
9 Know therefore that the Lord thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;
10 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.
11 Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day, to do them.
