The LORD said to Moshe, "Go to the people, and sanctify them today and tomorrow, and let them wash their garments,
and be ready against the third day; for on the third day the LORD will come down in the sight of all the people on Mount Sinai.
You shall set bounds to the people round about, saying, 'Be careful that you don't go up onto the mountain, or touch its border. Whoever touches the mountain shall be surely put to death.
No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.' When the shofar sounds long, they shall come up to the mountain."
Moshe went down from the mountain to the people, and sanctified the people; and they washed their clothes.
He said to the people, "Be ready by the third day. Don't have sexual relations with a woman."
It happened on the third day, when it was morning, that there were thunders and lightnings, and a thick cloud on the mountain, and the sound of an exceedingly loud shofar; and all the people who were in the camp trembled.
Moshe led the people out of the camp to meet God; and they stood at the lower part of the mountain.
Mount Sinai, the whole of it, smoked, because the LORD descended on it in fire; and its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly.
When the sound of the shofar grew louder and louder, Moshe spoke, and God answered him by a voice.
The LORD came down on Mount Sinai, to the top of the mountain. The LORD called Moshe to the top of the mountain, and Moshe went up.
The LORD said to Moshe, "Go down, charge the people, lest they break through to the LORD to gaze, and many of them perish.
Let the Kohanim also, who come near to the LORD, sanctify themselves, lest the LORD break forth on them."
Moshe said to the LORD, "The people can't come up to Mount Sinai, for you charged us, saying, 'Set bounds around the mountain, and sanctify it.'"
