Exodus 19:17-19

21st Century King James Version

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.

¹⁹ And when the voice of the trumpet sounded long and waxed louder and louder, Moses spoke, and God answered him by a voice.
