Deuteronomy 7:21-23

21st Century King James Version

²¹ Thou shalt not be frightened at them; for the Lord thy God is among you, a mighty God and fearsome.

²² And the Lord thy God will put out those nations before thee little by little; thou mayest not consume them at once, lest the beasts of the field increase upon thee.

²³ But the Lord thy God shall deliver them unto thee, and shall destroy them with a mighty destruction until they be destroyed.
