Exodus 34:27-29 Modern English Version (MEV)
27 Then the Lord said to Moses: Write down these words, for in accordance with these words I have made a covenant with you and with Israel. 28 So he was there with the Lord forty days and forty nights. He did not eat bread or drink water. And He wrote on the tablets the words of the covenant, the Ten Commandments.
Moses’ Radiant Face
29 When Moses came down from Mount Sinai with the two tablets of testimony in the hands of Moses, when he came down from the mountain, Moses did not know that the skin of his face shone while he talked with Him.
