Deuteronomy 7:7-15

“The LORD did not set His love on you nor choose you because you were more in number than any of the peoples, for you were the fewest of all peoples, but because the LORD loved you and kept the oath which He swore to your forefathers, the LORD brought you out by 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, He is God, the faithful God, who keeps His covenant and His lovingkindness to a thousandth generation with those who love Him and keep His commandments; but repays those who hate Him to their faces, to destroy them; He will not delay with him who hates Him, He will repay him to his face. Therefore, you shall keep the commandment and the statutes and the judgments which I am commanding you today, to do them. “Then it shall come about, because you listen to these judgments and keep and do them, that the LORD your God will keep with you His covenant and His lovingkindness which He swore to your forefathers. He will love you and bless you and multiply you; He will also bless the fruit of your womb and the fruit of your ground, your grain and your new wine and your oil, the increase of your herd and the young of your flock, in the land which He swore to your forefathers to give you. You shall be blessed above all peoples; there will be no male or female barren among you or among your cattle. The LORD will remove from you all sickness; and He will not put on you any of the harmful diseases of Egypt which you have known, but He will lay them on all who hate you.
