Deuteronomy 7:20

16You shall consume all the peoples whom the LORD your God shall deliver to you. Your eye shall not pity them. You shall not serve their gods; for that would be a snare to you.

17If you shall say in your heart, “These nations are more than I; how can I dispossess them?”

18you shall not be afraid of them. You shall remember well what the LORD your God did to Pharaoh and to all Egypt:

19the great trials which your eyes saw, the signs, the wonders, the mighty hand, and the outstretched arm, by which the LORD your God brought you out. So shall the LORD your God do to all the peoples of whom you are afraid.

20Moreover the LORD your God will send the hornet among them, until those who are left, and hide themselves, perish from before you.

21You shall not be scared of them; for the LORD your God is among you, a great and awesome God.

22The LORD your God will cast out those nations before you little by little. You may not consume them at once, lest the animals of the field increase on you.

23But the LORD your God will deliver them up before you, and will confuse them with a great confusion, until they are destroyed.

24He will deliver their kings into your hand, and you shall make their name perish from under the sky. No one will be able to stand before you until you have destroyed them.
