Exodus 19:10–19

¹⁰the Lord said to Moses, “Go to the people and consecrate them today and tomorrow. Have them wash their clothes^{* 11}and prepare for the third day, because on the third day the Lord will come down upon Mount Sinai in the sight of all the people.^{* 12}You shall set limits for the people all around, saying, ‘Be careful not to go up the mountain or to touch the edge of it. Any who touch the mountain shall be put to death.^{* 13}No hand shall touch them, but they shall be stoned or shot with arrows;ⁱ whether animal or human being, they shall not live.’ When the trumpet sounds a long blast, they may go up on the mountain.” ¹⁴So Moses went down from the mountain to the people. He consecrated the people, and they washed their clothes. ¹⁵And he said to the people, “Prepare for the third day; do not go near a woman.”

¹⁶On the morning of the third day there was thunder and lightning, as well as a thick cloud on the mountain and a blast of a trumpet so loud that all the people who were in the camp trembled.^{* 17}Moses brought the people out of the camp to meet God. They took their stand at the foot of the mountain. ¹⁸Now all of Mount Sinai was wrapped in smoke, because the Lord had descended upon it in fire; the smoke went up like the smoke of a kiln, while the whole mountain shook violently.^{* 19}As the blast of the trumpet grew louder and louder, Moses would speak and God would answer him in thunder.^*
