Exodus 19:16-18

LEB(i) 16 And* on the third day, when it was morning, there was thunder and lightning, and a heavy cloud over the mountain and a very loud ram's horn sound, and all the people who were in the camp trembled. 17 And Moses brought the people out from the camp to meet God, and they took their stand at the foot of the mountain. 18 And Mount Sinai was all wrapped in smoke because Yahweh went down on it in the fire, and its smoke went up like the smoke of a smelting furnace, and the whole mountain trembled greatly.
