Charles Ellicott Commentary Exodus 33:17

"And Jehovah said unto Moses, I will do this thing also that thou hast spoken; for thou hast found favor in my sight, and I know thee by name." — Exodus 33:17 (ASV)

I will do this thing also that you have spoken. —At length the promise is unambiguously given. Moses is rewarded for his persistence. God’s people have found grace in His sight. He will go up with them, and so separate them, or distinguish them, from all the people that are on the face of the earth. Now at last Moses is satisfied.
