Exodus 33:12-16
33:12 Moses said to the Lord, “See, you have been saying to me, ‘Bring this people up,’ but you have not let me know whom you will send with me. But you said, ‘I know you by name, and also you have found favor in my sight.’
33:13 Now if I have found favor in your sight, show me your way, that I may know you, that I may continue to find favor in your sight. And see that this nation is your people.”
33:14 And the Lord said, “My presence will go with you, and I will give you rest.”
33:15 And Moses said to him, “If your presence does not go with us, do not take us up from here.
33:16 For how will it be known then that I have found favor in your sight, I and your people? Is it not by your going with us, so that we will be distinguished, I and your people, from all the people who are on the face of the earth?”
