**16** Then it came to pass on the third day, in the morning, that there were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled. **17** And Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain. **18** Now Mount Sinai was completely in smoke, because the Lord descended upon it in fire. Its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly. **19** And when the blast of the trumpet sounded long and became louder and louder, Moses spoke, and God answered him by voice.
