Deuteronomy 9:1-3

1“Hear, O Israel! You are crossing the Jordan today to go in to dispossess nations greater and more powerful than you, great cities fortified to heaven,

2a people great and tall, sons of Anakim, whom you know and of whom you have heard it said, ‘Who can stand before the sons of Anak?’

3So know today [with confident assurance] that the Lord your God is crossing [the Jordan] before you like a devouring fire. He will destroy them and He will subdue them before you, and you shall drive them out and destroy them quickly, just as the Lord has promised you.
