Deuteronomy 7:8-10

8 But because the LORD loves you and is keeping the oath which He swore to your fathers, the LORD has brought you out with a mighty hand and redeemed (bought) you from the house of slavery, from the hand of Pharaoh king of Egypt.

9 Therefore know [without any doubt] and understand that the LORD your God, He is God, the faithful God, who is keeping His covenant and His [steadfast] lovingkindness to a thousand generations with those who love Him and keep His commandments;

10 but repays those who hate Him to their faces, by destroying them; He will not hesitate with him who hates Him, He will repay him to his face.
