Exodus 19:10-14

New King James Version

¹⁰ Then the Lord said to Moses, “Go to the people and ^(A)consecrate them today and tomorrow, and let them wash their clothes. ¹¹ And let them be ready for the third day. For on the third day the Lord will come down upon Mount Sinai in the sight of all the people. ¹² You shall set bounds for the people all around, saying, ‘Take heed to yourselves that you do not go up to the mountain or touch its base. ^(B)Whoever touches the mountain shall surely be put to death. ¹³ Not a hand shall touch him, but he shall surely be stoned or shot with an arrow; whether man or beast, he shall not live.’ When the trumpet sounds long, they shall come near the mountain.”

¹⁴ So Moses went down from the mountain to the people and sanctified the people, and they washed their clothes.
