12 Put boundaries for the people all around the mountain and say: Be careful that you don’t go up on the mountain or touch its base. Anyone who touches the mountain will be put to death.
13 No hand may touch him; instead he will be stoned or shot with arrows. No animal or man will live. When the ram’s horn sounds a long blast, they may go up the mountain.”
14 Then Moses came down from the mountain to the people and consecrated them, and they washed their clothes.
15 He said to the people, “Be prepared by the third day. Do not have sexual relations with women.”
16 On the third day, when morning came, there was thunder and lightning, a thick cloud on the mountain, and a loud trumpet sound, so that all the people in the camp shuddered.
17 Then Moses brought the people out of the camp to meet God, and they stood at the foot of the mountain.
18 Mount Sinai was completely enveloped in smoke because the Lord came down on it in fire. Its smoke went up like the smoke of a furnace, and the whole mountain shook violently.
