Exodus 19:7-19:19

Moses came and summoned the elders of the people and put before them all that the Lord had commanded him. All the people answered as one, saying, "All that the Lord has spoken we will do!" And Moses brought back the people's words to the Lord. And the Lord said to Moses, "I will come to you in a thick cloud, in order that the people may hear when I speak with you and so trust you ever after." Then Moses reported the people's words to the Lord, and the Lord said to Moses, "Go to the people and warn them to stay pure today and tomorrow. Let them wash their clothes. Let them be ready for the third day; for on the third day the Lord will come down, in the sight of all the people, on Mount Sinai. You shall set bounds for the people round about, saying, 'Beware of going up the mountain or touching the border of it. Whoever touches the mountain shall be put to death: no hand shall touch him, but he shall be either stoned or shot; beast or man, he shall not live.' When the ram's horn sounds a long blast, they may go up on the mountain." Moses came down from the mountain to the people and warned the people to stay pure, and they washed their clothes. And he said to the people, "Be ready for the third day: do not go near a woman." On the third day, as morning dawned, there was thunder, and lightning, and a dense cloud upon the mountain, and a very loud blast of the horn; and all the people who were in the camp trembled. Moses led the people out of the camp toward God, and they took their places at the foot of the mountain. Now Mount Sinai was all in smoke, for the Lord had come down upon it in fire; the smoke rose like the smoke of a kiln, and the whole mountain trembled violently. The blare of the horn grew louder and louder. As Moses spoke, God answered him in thunder.
