Deuteronomy 7:20-22

New King James Version

^20 (A)Moreover the Lord your God will send the hornet among them until those who are left, who hide themselves from you, are destroyed. ²¹ You shall not be terrified of them; for the Lord your God, the great and awesome God, is among you. ²² And the Lord your God will drive out those nations before you ^(B)little by little; you will be unable to ^[a]destroy them at once, lest the beasts of the field become too numerous for you.
