2After they departed from Rephidim, they entered the Wilderness of Sinai and camped in the wilderness, and Israel camped there in front of the mountain.
3Moses went up the mountain to God, and the LORD called to him from the mountain: "This is what you must say to the house of Jacob, and explain to the Israelites:
9The LORD said to Moses, "I am going to come to you in a dense cloud, so that the people will hear when I speak with you and will always believe you." Then Moses reported the people's words to the LORD.
12Put 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.
13No 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."
16On 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.
18Mount 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.
23But Moses responded to the LORD, "The people cannot come up Mount Sinai, since You warned us: Put a boundary around the mountain and consider it holy."
24And the LORD replied to him, "Go down and come back with Aaron. But the priests and the people must not break through to come up to the LORD, or He will break out in anger against them."
