20. The Lord came down on the top of Mount Sinai and called Moses to the top of the mountain. Moses went up
21. and the Lord said to him, “Go down and warn the people not to cross the boundary to come and look at me; if they do, many of them will die.
22. Even the priests who come near me must purify themselves, or I will punish them.”
23. Moses said to the Lord, “The people cannot come up, because you commanded us to consider the mountain sacred and to mark a boundary round it.”
