15 And he said unto the people, Be ready against the third day: come not near a woman.
16 And it came to pass on the third day, when it was morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of a trumpet exceeding loud; and all the people that were in the camp trembled.
17 And Moses brought forth the people out of the camp to meet God; and they stood at the nether part of the mount.
18 And mount Sinai was altogether on smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.
19 And when the voice of the trumpet waxed louder and louder, Moses spake, and God answered him by a voice.
20 And the LORD came down upon mount Sinai, to the top of the mount: and the LORD called Moses to the top of the mount; and Moses went up.
21 And the LORD said unto Moses, Go down, charge the people, lest they break through unto the LORD to gaze, and many of them perish.
