Deuteronomy 7:21-23

King James Version

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

²² And the Lord thy God will put out those nations before thee by little and 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.
