Charles Ellicott Commentary Deuteronomy 9:5

"Not for thy righteousness, or for the uprightness of thy heart, dost thou go in to possess their land; but for the wickedness of these nations Jehovah thy God doth drive them out from before thee, and that he may establish the word which Jehovah sware unto thy fathers, to Abraham, to Isaac, and to Jacob." — Deuteronomy 9:5 (ASV)

Not for thy righteousness ... dost thou go. —The pronoun is emphatic. There is no reason why you of all others should be honored in this way.
