Exodus 19:15

¹³A hand shall not touch it, for everyone that touches shall be stoned with stones or shot through with a dart, whether beast or whether man, it shall not live: when the voices and trumpets and cloud depart from off the mountain, they shall come up on the mountain.

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

— Exodus 19:15 —

¹⁶And it came to pass on the third day, as the morning drew nigh, there were voices and lightnings and a dark cloud on Mount Sinai: the voice of the trumpet sounded loud, and all the people in the camp trembled.

¹⁷And Moses led the people forth out of the camp to meet God, and they stood by under the camp.
