Deuteronomy 7:14-20

You will be blessed more than any other people; none of your men or women will be childless, nor will any of your livestock be without young. The LORD will keep you free from every disease. He will not inflict on you the horrible diseases you knew in Egypt, but he will inflict them on all who hate you. You must destroy all the peoples the LORD your God gives over to you. Do not look on them with pity and do not serve their gods, for that will be a snare to you. You may say to yourselves, “These nations are stronger than we are. How can we drive them out?” But do not be afraid of them; remember well what the LORD your God did to Pharaoh and to all Egypt. You saw with your own eyes the great trials, the signs and wonders, the mighty hand and outstretched arm, with which the LORD your God brought you out. The LORD your God will do the same to all the peoples you now fear. Moreover, the LORD your God will send the hornet among them until even the survivors who hide from you have perished.
