Exodus 19:10-25

10Adonai said to Moses, “Go to the people, and sanctify them today and tomorrow. Let them wash their clothing.

11Be ready for the third day. For on the third day Adonai will come down upon Mount Sinai in the sight of all the people.

12You are to set boundaries for the people all around, saying, ‘Be very careful not to go up onto the mountain, or touch the border of it. Whoever touches the mountain will surely be put to death.

13Not a hand is to touch it, but he will surely be stoned or shot through. Whether it is an animal or a man, it will not live.’ When the shofar sounds, they may come up to the mountain.”

14Then Moses went down from the mountain to the people, consecrated them, and then, they washed their clothing.

15He said to the people, “Be ready for the third day. Do not draw near your wives.”

16In the morning of the third day, there was thundering and lightning, a thick cloud on the mountain, and the blast of an exceedingly loud shofar. All the people in the camp trembled.

17Then Moses brought the people out of the camp to meet God, and they stood at the lowest part of the mountain.

18Now the entire Mount Sinai was in smoke, because Adonai had descended upon it in fire. The smoke ascended like the smoke of a furnace. The whole mountain quaked greatly.

19When the sound of the shofar grew louder and louder, Moses spoke, and God answered him with a thunderous sound.

20Then Adonai came down onto Mount Sinai, to the top of the mountain. Adonai called Moses to the top of the mountain, so Moses went up.

21Then Adonai said to Moses, “Go down and warn the people, lest they break through to see Adonai, and many of them die.

22Even the kohanim who come near to Adonai must consecrate themselves, so that Adonai does not break out against them.”

23Moses said to Adonai, “The people cannot come up to Mount Sinai, for You are the One who warned us, saying, ‘Set boundaries around the mountain, and consecrate it.’”

24Then Adonai said to him, “Go down. You are to come back up, you and Aaron with you. But do not let the kohanim and the people break through to come up to Adonai, or He will break out against them.”

25So Moses went down to the people and told them.
