Ex 19:1-15
Arrival at Sinai. 1a In the third month after the Israelites’ departure from the land of Egypt, on the first day, they came to the wilderness of Sinai. 2After they made the journey from Rephidim and entered the wilderness of Sinai, they then pitched camp in the wilderness.*
While Israel was encamped there in front of the mountain, 3Moses went up to the mountain of God. Then the LORD called to him from the mountain, saying: This is what you will say to the house of Jacob; tell the Israelites: 4You have seen how I treated the Egyptians and how I bore you up on eagles’ wings and brought you to myself.b 5Now, if you obey me completely and keep my covenant,* you will be my treasured possession among all peoples,c though all the earth is mine. 6You will be to me a kingdom of priests,* a holy nation.d That is what you must tell the Israelites. 7So Moses went and summoned the elders of the people. When he set before them all that the LORD had ordered him to tell them, 8all the people answered together, “Everything the LORD has said, we will do.” Then Moses brought back to the LORD the response of the people.
9The LORD said to Moses: I am coming to you now in a dense cloud,e so that when the people hear me speaking with you, they will also remain faithful to you.
When Moses, then, had reported the response of the people to the LORD, 10the LORD said to Moses: Go to the people and have them sanctify themselves today and tomorrow. Have them wash their garments 11and be ready for the third day; for on the third day the LORD will come down on Mount Sinai in the sight of all the people. 12Set limits for the people all around,f saying: Take care not to go up the mountain, or even to touch its edge. All who touch the mountain must be put to death. 13No hand shall touch them, but they must be stoned to death or killed with arrows. Whether human being or beast, they must not be allowed to live. Only when the ram’s horn sounds may they go up on the mountain.* 14Then Moses came down from the mountain to the people and had them sanctify themselves, and they washed their garments. 15He said to the people, “Be ready for the third day. Do not approach a woman.”
