Exodus 33:14-16

14The LORD replied, “My Presence will go with you, and I will give you rest.” 15Then Moses said to him, “If your Presence does not go with us, do not send us up from here.

16How will anyone know that you are pleased with me and with your people unless you go with us? What else will distinguish me and your people from all the other people on the face of the earth?”
