Deuteronomy 7:17-21

King James Version

¹⁷ If thou shalt say in thine heart, These nations are more than I; how can I dispossess them?

¹⁸ Thou shalt not be afraid of them: but shalt well remember what the Lord thy God did unto Pharaoh, and unto all Egypt;

¹⁹ The great temptations which thine eyes saw, and the signs, and the wonders, and the mighty hand, and the stretched out arm, whereby the Lord thy God brought thee out: so shall the Lord thy God do unto all the people of whom thou art afraid.

²⁰ Moreover the Lord thy God will send the hornet among them, until they that are left, and hide themselves from thee, be destroyed.

²¹ Thou shalt not be affrighted at them: for the Lord thy God is among you, a mighty God and terrible.
