Exodus 19:14 BBE

¹²  And let limits be marked out for the people round the mountain, and say to them, Take care not to go up the mountain or near the sides of it: whoever puts his foot on the mountain will certainly come to his death:

¹³  He is not to be touched by a hand, but is to be stoned or have an arrow put through him; man or beast, he is to be put to death: at the long sounding of a horn they may come up to the mountain.

¹⁴  Then Moses went down from the mountain to the people, and made the people holy; and their clothing was washed.

¹⁵  And he said to the people, Be ready by the third day: do not come near a woman.

¹⁶  And when morning came on the third day, there were thunders and flames and a thick cloud on the mountain, and a horn sounding very loud; and all the people in the tents were shaking with fear.
