Exodus 19:16-18

Brenton(i) 16 And it came to pass on the third day, as the morning drew nigh, there were voices and lightnings and a dark cloud on mount Sina: the voice of the trumpet sounded loud, and all the people in the camp trembled. 17 And Moses led the people forth out of the camp to meet God, and they stood by under the camp. 18 The mount of Sina was altogether on a smoke, because God had descended upon it in fire; and the smoke went up as the smoke of a furnace, and the people were exceedingly amazed.
