Rashi on Deuteronomy
ויאמר ה' אלי וגו׳ AND THE LORD SPAKE TO ME, [ARISE, GO ON THE JOURNEY BEFORE THE PEOPLE] — Although you had turned away from Him and had sinned by worshipping the golden calf, yet He said to me, (Exodus 32:34) “Go, lead the people”.
Sforno on Deuteronomy
ויבואו ויירשו את הארץ אשר נשבעתי, if not for G’d’s oath you would not have merited to inherit it due to your excessive rebelliousness.
Siftei Chakhamim
Although you turned away from Him, etc. Otherwise why is this verse mentioned during [Moshe’s] words of rebuke?
