9. Then the Lord said to Moses, "I’m about to come to you in a thick cloud in order that the people will hear me talking with you so that they will always trust you."Moses told the Lord what the people said,
10. and the Lord said to Moses: "Go to the people and take today and tomorrow to make them holy. Have them wash their clothes.
11. Be ready for the third day, because on the third day the Lord will come down on Mount Sinai for all the people to see.
12. Set up a fence for the people all around and tell them, ‘Be careful not to go up the mountain or to touch any part of it.’ Anyone who even touches the mountain must be put to death.
13. No one should touch anyone who has touched it, or they must be either stoned to death or shot with arrows. Whether an animal or a human being, they must not be allowed to live. Only when the ram’s horn sounds may they go up on the mountain."
14. So Moses went down the mountain to the people. He made sure the people were holy and that they washed their clothes.
15. He told the men, "Prepare yourselves for three days. Don’t go near a woman."
16. When morning dawned on the third day, there was thunder, lightning, and a thick cloud on the mountain, and a very loud blast of a horn. All the people in the camp shook with fear.
17. Moses brought the people out of the camp to meet God, and they took their place at the foot of the mountain.
18. Mount Sinai was all in smoke because the Lord had come down on it with lightning. The smoke went up like the smoke of a hot furnace, while the whole mountain shook violently.
