Deuteronomy 7:12

8but because the LORD loves you, and because he desires to keep the oath which he swore to your fathers, the LORD has brought you out with a mighty hand and redeemed you out of the house of bondage, from the hand of Pharaoh king of Egypt.

9Know therefore that the LORD your God himself is God, the faithful God, who keeps covenant and loving kindness to a thousand generations with those who love him and keep his commandments,

10and repays those who hate him to their face, to destroy them. He will not be slack to him who hates him. He will repay him to his face.

11You shall therefore keep the commandments, the statutes, and the ordinances which I command you today, to do them.

12It shall happen, because you listen to these ordinances and keep and do them, that the LORD your God will keep with you the covenant and the loving kindness which he swore to your fathers.

13He will love you, bless you, and multiply you. He will also bless the fruit of your body and the fruit of your ground, your grain and your new wine and your oil, the increase of your livestock and the young of your flock, in the land which he swore to your fathers to give you.

14You will be blessed above all peoples. There won’t be male or female barren among you, or among your livestock.

15The LORD will take away from you all sickness; and he will put none of the evil diseases of Egypt, which you know, on you, but will lay them on all those who hate you.

16You shall consume all the peoples whom the LORD your God shall deliver to you. Your eye shall not pity them. You shall not serve their gods; for that would be a snare to you.
