Deuteronomy 7:15-17

Amplified Bible

¹⁵ The Lord will take away from you all sickness; and He will not subject you to any of the harmful diseases of Egypt which you have known, but He will impose them on all [those] who hate you. ¹⁶ And you shall consume all the peoples whom the Lord your God will give over to you; your eye shall not pity them, nor shall you serve their gods, for that would be a [deadly] trap to you.

¹⁷ “If you say in your heart, ‘These nations are greater than I am; how can I dispossess them?’
