Deuteronomy 7:15-19

And the Lord will remove from you all sickness; and He will not inflict upon you any of the harmful diseases of Egypt which you have known, but He will give them to all who hate you.

You shall consume all the peoples whom the Lord your God will turn over to you; your eye shall not pity them, nor shall you serve their gods, for that would be a snare to you.

“If you say in your heart, ‘These nations are greater than I; how can I dispossess them?’

you are not to be afraid of them; you shall remember well what the Lord your God did to Pharaoh and to all Egypt:

the great trials which your eyes saw and the signs and the wonders, and the mighty hand and the outstretched arm by which the Lord your God brought you out. The Lord your God will do the same to all the peoples of whom you are afraid.
