Exodus 33:12

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.’

Exodus 33:16

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?”
