Deuteronomy 7:16

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.

17If you shall say in your heart, “These nations are more than I; how can I dispossess them?”

18you shall not be afraid of them. You shall remember well what the LORD your God did to Pharaoh and to all Egypt:

19the great trials which your eyes saw, the signs, the wonders, the mighty hand, and the outstretched arm, by which the LORD your God brought you out. So shall the LORD your God do to all the peoples of whom you are afraid.

20Moreover the LORD your God will send the hornet among them, until those who are left, and hide themselves, perish from before you.
