Deuteronomy 9:1-4

1Hear, O Israel: Thou art to pass over Jordan this day, to go in to possess nations greater and mightier than thyself, cities great and fortified up to heaven,

2A people great and tall, the children of the Anakims, whom thou knowest, and of whom thou hast heard it said, Who can stand before the children of Anak!

3Understand therefore this day, that the LORD thy God is he who goeth over before thee; as a consuming fire he shall destroy them, and he shall bring them down before thy face: so shalt thou drive them out, and destroy them quickly, as the LORD hath said to thee.

4Speak not thou in thy heart, after that the LORD thy God hath cast them out from before thee, saying, For my righteousness the LORD hath brought me in to possess this land: but for the wickedness of these nations the LORD doth drive them out from before thee.
