9 The Lord said to Moses, “I am going to come to you in a dense cloud, so that the people will hear when I speak with you and will always believe you.” Then Moses reported the people’s words to the Lord.
10 And the Lord told Moses, “Go to the people and consecrate them today and tomorrow. They must wash their clothes
11 and be prepared by the third day, for on the third day the Lord will come down on Mount Sinai in the sight of all the people.
12 Put boundaries for the people all around the mountain and say: Be careful that you don’t go up on the mountain or touch its base. Anyone who touches the mountain will be put to death.
13 No hand may touch him; instead he will be stoned or shot with arrows. No animal or man will live. When the ram’s horn sounds a long blast, they may go up the mountain.”
14 Then Moses came down from the mountain to the people and consecrated them, and they washed their clothes.
15 He said to the people, “Be prepared by the third day. Do not have sexual relations with women.”
