Exodus 33:15-17

Then Moses said to him, “If you yourself don’t go with us, then don’t send us away from this place. If you don’t go with us, no one will know that you are pleased with me and with your people. These people and I will be no different from any other people on earth.” Then the LORD said to Moses, “I will do what you ask, because I know you very well, and I am pleased with you.”
