Exodus 19:16-18

ISV(i) 16 The LORD Appears on Mount SinaiWhen morning came on the third day, there was thunder and lightning, with a heavy cloud over the mountain, and the very loud sound of a ram’s horn. All the people in the camp trembled. 17 Moses brought the people from the camp to meet God, and they stood at the base of the mountain. 18 Mount Sinai was completely enveloped in smoke because the LORD had come down in fire on it. Smoke went up from it like smoke from a kiln, and the whole mountain shook violently.
