Deuteronomy 7:8-10

Complete Jewish Bible

⁸ Rather, it was because Adonai loved you, and because he wanted to keep the oath which he had sworn to your ancestors, that Adonai brought you out with a strong hand and redeemed you from a life of slavery under the hand of Pharaoh king of Egypt. (Maftir) ⁹ From this you can know that Adonai your God is indeed God, the faithful God, who keeps his covenant and extends grace to those who love him and observe his mitzvot, to a thousand generations. ¹⁰ But he repays those who hate him to their face and destroys them. He will not be slow to deal with someone who hates him; he will repay him to his face.
