Deuteronomy 7:21-23

World English Bible

²¹ You shall not be scared of them; for Yahweh your God is among you, a great and awesome God. ²² Yahweh 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. ²³ But Yahweh your God will deliver them up before you, and will confuse them with a great confusion, until they are destroyed.
