Exodus 33:14-16

And He said, “My presence shall go with you, and I will give you rest.” Then he said to Him, “If Your presence does not go with us, do not lead us up from here. For how then can it be known that I have found favor in Your sight, I and Your people? Is it not by Your going with us, so that we, I and Your people, may be distinguished from all the other people who are upon the face of the earth?”
