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.”
