Deuteronomy 9:1-4

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

2a people great and tall, the sons of the Anakim, whom thou knowest, and of whom thou hast heard say, Who can stand before the sons of Anak?

3Know therefore this day, that Jehovah thy God is he who goeth over before thee as a devouring fire; he will destroy them, and he will bring them down before thee: so shalt thou drive them out, and make them to perish quickly, as Jehovah hath spoken unto thee.

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