Exodus 33:18-20
Then he (Moses) said, “Please, show me Your glory!”
So He (the Lord) said, “I will cause all My goodness to pass before you, and call out the Name of Adonai before you. I will be gracious toward whom I will be gracious, and I will show mercy on whom I will be merciful.” But He also said, “You cannot see My face, for no man can see Me and live.”
