Deuteronomy 7:20-22

21st Century King James Version

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

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.
