Deuteronomy 7:14–16

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