Deuteronomy 9:1-4

1“Hear, O Israel! You are about to cross over the Jordan today, to go in to dispossess nations greater and mightier than yourself—cities great and fortified up to the heavens.

2The people are great and tall, sons of the Anakim. You know them, and you yourselves have heard, “Who can stand before the sons of Anak?”

3But you will know today that Adonai your God is the One who is crossing over before you as a devouring fire. He will destroy them, and He will bring them down before you, so that you may drive them out and make them perish quickly, as Adonai has promised you.

4“After Adonai your God has driven them out from before you, do not say in your heart, ‘It is because of my righteousness that Adonai has brought me in to possess this land.’ It is because of the wickedness of these nations that Adonai is driving them out from before you.
