10 And the Lord said unto Moses, Go unto the people, and sanctify them today and tomorrow, and let them wash their clothes,
11 and be ready against the third day: for the third day the Lord will come down in the sight of all the people upon mount Si´nai.
12 And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death:
13 there shall not a hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount.
14 And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.
15 And he said unto the people, Be ready against the third day: come not at your wives.
16 And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.
