Deuteronomy 7:8-10

New Catholic Bible

⁸ It was because the Lord loved you and was keeping the promise that he had sworn to your fathers that the Lord brought you out with a mighty hand and redeemed you from the hand of Pharaoh, the king of Egypt, from the land of your slavery.

⁹ Keep in mind, therefore, that the Lord, your God, is God. He is a faithful God who keeps his covenant of mercy to the thousandth generation toward those who love him and observe his commandments. ¹⁰ But upon those who hate him, he will avenge himself face to face, wiping them out. He will not delay in avenging himself face to face with those who hate him.^[a]
