Deuteronomy 9:1, 4

Hear, 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

Speak 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.
