Deuteronomy 7:8-10

King James Version

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.
