Exodus 19:16-18

21st Century King James Version

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 who 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 nether part of the mount.

¹⁸ And Mount Sinai was altogether in 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.
