Then the Lord said to Moses, "Write down these words, for in accordance with them I have made a covenant with you and with Israel." So Moses stayed there with the Lord for forty days and forty nights, without eating any food or drinking any water, and he wrote on the tablets the words of the covenant, the ten commandments.
As Moses came down from Mount Sinai with the two tablets of the commandments in his hands, he did not known that the skin of his face had become radiant while he conversed with the Lord. When Aaron, then, and the other Israelites saw Moses and noticed how radiant the skin of his face had become, they were afraid to come near him. Only after Moses called to them did Aaron and all the rulers of the community come back to him. Moses then spoke to them. Later on, all the Israelites came up to him, and he enjoined on them all that the Lord had told him on Mount Sinai. When he finished speaking with them, he put a veil over his face. Whenever Moses entered the presence of the Lord to converse with him, he removed the veil until he came out again. On coming out, he would tell the Israelites all that had been commanded. Then the Israelites would see that the skin of Moses' face was radiant; so he would again put the veil over his face until he went in to converse with the Lord.
