Put limits for the people around the mountain and tell them, ‘Be careful that you do not approach the mountain or touch the foot of it. Whoever touches the mountain is to be put to death.
They are to be stoned or shot with arrows; not a hand is to be laid on them. No person or animal shall be permitted to live.’ Only when the ram’s horn sounds a long blast may they approach the mountain.”
After Moses had gone down the mountain to the people, he consecrated them, and they washed their clothes.
Then he said to the people, “Prepare yourselves for the third day. Abstain from sexual relations.”
On the morning of the third day there was thunder and lightning, with a thick cloud over the mountain, and a very loud trumpet blast. Everyone in the camp trembled.
Then Moses led the people out of the camp to meet with God, and they stood at the foot of the mountain.
Mount Sinai was covered with smoke, because the LORD descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountain trembled violently.
As the sound of the trumpet grew louder and louder, Moses spoke and the voice of God answered him.
The LORD descended to the top of Mount Sinai and called Moses to the top of the mountain. So Moses went up
and the LORD said to him, “Go down and warn the people so they do not force their way through to see the LORD and many of them perish.
Even the priests, who approach the LORD, must consecrate themselves, or the LORD will break out against them.”
