8. And all the people responded together, “We will do everything the lord has commanded.” So Moses brought the people’s answer back to the lord.
9. Then the lord said to Moses, “I will come to you in a thick cloud, Moses, so the people themselves can hear me when I speak with you. Then they will always trust you.”Moses told the lord what the people had said.
10. Then the lord told Moses, “Go down and prepare the people for my arrival. Consecrate them today and tomorrow, and have them wash their clothing.
11. Be sure they are ready on the third day, for on that day the lord will come down on Mount Sinai as all the people watch.
12. Mark off a boundary all around the mountain. Warn the people, ‘Be careful! Do not go up on the mountain or even touch its boundaries. Anyone who touches the mountain will certainly be put to death.
13. No hand may touch the person or animal that crosses the boundary; instead, stone them or shoot them with arrows. They must be put to death.’ However, when the ram’s horn sounds a long blast, then the people may go up on the mountain.”
14. So Moses went down to the people. He consecrated them for worship, and they washed their clothes.
15. He told them, “Get ready for the third day, and until then abstain from having sexual intercourse.”
