Deuteronomy 9:1-4

1Hear, Israel! Thou art to pass over the Jordan this day, to enter in to possess nations greater and mightier than thou, cities great and walled 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 then this day, that Jehovah thy 1God is he that goeth over before thee, a consuming fire; he will destroy them, and he will cast them down before thee, and thou shalt dispossess them and cause them to perish quickly, as Jehovah hath said unto thee.

4Thou shalt not say in thy heart, when Jehovah thy 2God thrusteth them out from before thee, saying, For my righteousness Jehovah hath brought me in to possess this land; but for the wickedness of these nations doth Jehovah dispossess them from before thee.
