Exodus 19:17-19

New Catholic Bible

¹⁷ Moses brought the people out of the camp to meet God. They stood on foot at the base of the mountain.

¹⁸ Mount Sinai was wrapped in smoke, for the Lord had descended upon it in fire and the smoke rose up like the smoke of a furnace. The entire mountain trembled. ¹⁹ The sound of the trumpet grew louder and louder. Moses spoke and God responded with the sound of a trumpet.
