Exodus 33:17-20

The LORD answered Moses, “I will do this very thing you have asked, for you have found favor with me, and I know you by name.” Then Moses said, “Please, let me see your glory.” He said, “I will cause all my goodness to pass in front of you, and I will proclaim the name ‘the LORD’ before you. I will be gracious to whom I will be gracious, and I will have compassion on whom I will have compassion.” But he added, “You cannot see my face, for humans cannot see me and live.”
