Exodus 33:20 - 34:3
This reading is from the special Torah portion read on the Shabbat during Passover, Parshat Pesach, Exodus 33:12-34:26.
"But," He said, "you cannot see My face, for man may not see Me and live." And the Lord said, "See, there is a place near Me. Station yourself on the rock and, as My Presence passes by, I will put you in a cleft of the rock and shield you with My hand until I have passed by. Then I will take My hand away and you will see My back; but My face must not be seen."
The Lord said to Moses: "Carve two tablets of stone like the first, and I will inscribe upon the tablets the words that were on the first tablets, which you shattered. Be ready by morning, and in the morning come up to Mount Sinai and present yourself there to Me, on the top of the mountain. No one else shall come up with you, and no one else shall be seen anywhere on the mountain; neither shall the flocks and the herds graze at the foot of this mountain."
