Exodus 19:10

Moses came and called for the elders of the people, and set before them all these words which the LORD commanded him.

All the people answered together, and said, “All that the LORD has spoken we will do.”

Moses reported the words of the people to the LORD.

The LORD said to Moses, “Behold, I come to you in a thick cloud, that the people may hear when I speak with you, and may also believe you forever.” Moses told the words of the people to the LORD.

and 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 to the people all around, saying, ‘Be careful that you don’t go up onto the mountain, or touch its border. Whoever touches the mountain shall be surely put to death.

No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.’ When the trumpet sounds long, they shall come up to the mountain.”
