Shemot 33:12-19

And Moshe said unto HASHEM, See, Thou sayest unto me, Bring this people onward; and Thou hast not let me know whom Thou wilt send with me. Yet Thou hast said, I know thee by shem, and thou hast also found chen (grace, unmerited favor) in My sight. Therefore, now, if I have found chen in Thy sight, show me now Thy Derech, that I may have da'as of Thee, that I may find chen in Thy sight; and consider that this nation is Thy people. And He said, My Presence shall go with thee, and I will give thee rest. And he said unto Him, If Thy Presence go not with me, bring us not up from here. For how then shall it be known that I and Thy people have found chen in Thy sight? Is it not in that Thou goest with us? So shall we be made distinct as separate, I and Thy people, from all the people that are upon the face of ha'adamah. And HASHEM said unto Moshe, I will do this thing also that thou hast spoken; for thou hast found chen in My sight, and I know thee by shem. And he said, show me now Thy kavod. And He said, I will make kol tuvi (all My goodness) pass in front of thee, and I will call out with the Shem of HASHEM before thee; and will be gracious to whom I will be gracious, and will show rachamim on whom I will show rachamim.
