Exodus 19:16–25

¹⁶On the morning of the third day, thunder roared and lightning flashed, and a dense cloud came down on the mountain. There was a long, loud blast from a ram’s horn, and all the people trembled. ¹⁷Moses led them out from the camp to meet with God, and they stood at the foot of the mountain. ¹⁸All of Mount Sinai was covered with smoke because the Lord had descended on it in the form of fire. The smoke billowed into the sky like smoke from a brick kiln, and the whole mountain shook violently. ¹⁹As the blast of the ram’s horn grew louder and louder, Moses spoke, and God thundered his reply. ²⁰The Lord came down on the top of Mount Sinai and called Moses to the top of the mountain. So Moses climbed the mountain.

²¹Then the Lord told Moses, “Go back down and warn the people not to break through the boundaries to see the Lord, or they will die. ²²Even the priests who regularly come near to the Lord must purify themselves so that the Lord does not break out and destroy them.”

²³“But Lord,” Moses protested, “the people cannot come up to Mount Sinai. You already warned us. You told me, ‘Mark off a boundary all around the mountain to set it apart as holy.’ ”

²⁴But the Lord said, “Go down and bring Aaron back up with you. In the meantime, do not let the priests or the people break through to approach the Lord, or he will break out and destroy them.”

²⁵So Moses went down to the people and told them what the Lord had said.
