Deuteronomy 7:21-24

You shall not dread them, for the LORD your God is in your midst, a great and awesome God. The LORD your God will clear away these nations before you little by little; you will not be able to put an end to them quickly, for [if you did] the wild animals would become too numerous for you. But the LORD your God will hand them over to you, and will confuse them with a great panic until they are destroyed. And He will hand over their kings to you, and you will make their name perish from under heaven; no man will be able to stand before you until you have destroyed them.
