Exodus 19:10–15
Then the LORD said to Moses, “Go to the people and consecrate them today and tomorrow. They must wash their clothes / 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. / And you are to set up a boundary for the people around the mountain and tell them, ‘Be careful not to go up on the mountain or touch its base. Whoever touches the mountain shall surely be put to death.
