Deuteronomy 7:6-16 ESV
“For you are a people holy to the LORD your God. The LORD your God has chosen you to be a people for his treasured possession, out of all the peoples who are on the face of the earth. It was not because you were more in number than any other people that the LORD set his love on you and chose you, for you were the fewest of all peoples, but it is because the LORD loves you and is keeping the oath that he swore to your fathers, that the LORD has brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt. Know therefore that the LORD your God is God, the faithful God who keeps covenant and steadfast love with those who love him and keep his commandments, to a thousand generations, and repays to their face those who hate him, by destroying them. He will not be slack with one who hates him. He will repay him to his face. You shall therefore be careful to do the commandment and the statutes and the rules that I command you today. “And because you listen to these rules and keep and do them, the LORD your God will keep with you the covenant and the steadfast love that he swore to your fathers. He will love you, bless you, and multiply you. He will also bless the fruit of your womb and the fruit of your ground, your grain and your wine and your oil, the increase of your herds and the young of your flock, in the land that he swore to your fathers to give you. You shall be blessed above all peoples. There shall not be male or female barren among you or among your livestock. And the LORD will take away from you all sickness, and none of the evil diseases of Egypt, which you knew, will he inflict on you, but he will lay them on all who hate you. And you shall consume all the peoples that the LORD your God will give over to you. Your eye shall not pity them, neither shall you serve their gods, for that would be a snare to you.
