Exodus 19:10-15

10the Lord said to Moses, “Go to the people and aconsecrate them today and tomorrow, and let them bwash their garments 11and be ready for the third day. For on the third day cthe Lord will come down on Mount Sinai in the sight of all the people. 12And you shall set limits for the people all around, saying, ‘Take care not to go up into the mountain or touch the edge of it. dWhoever touches the mountain shall be put to death. 13No hand shall touch him, but he shall be stoned or shot;
That is,  shot with an arrow
whether beast or man, he shall not live.’ When fthe trumpet sounds a long blast, they shall come up to the mountain.”
14So Moses gwent down from the mountain to the people and hconsecrated the people; iand they washed their garments. 15And he said to the people, “Be ready for the jthird day; kdo not go near a woman.”
