15 And he said unto the people, Be ready against the third day; come not at your women.
16 And it came to pass on the third day when the morning came, that there were thunders and lightnings and a thick cloud upon the mount and the voice of the shofar {ram’s horn} exceeding loud, so that all the people that were in the camp trembled.
17 And Moses brought forth the people out of the camp to meet with God, and they stood at the lower part of the mount.
18 And all Mount Sinai smoked because the Lord had descended upon it in fire, and its smoke ascended as the smoke of a furnace, and the whole mount quaked greatly.
19 And the voice of the shofar sounded long and waxed louder and louder; Moses spoke, and God answered him by a voice.
20 And the Lord came down upon Mount Sinai, on the top of the mount, and the Lord called Moses up 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 the bounds to gaze upon the Lord, and many of them perish.
