Exodus 19:18-20

CAB(i) 18 Now Mount Sinai was altogether in smoke, because God had descended upon it in fire; and the smoke went up like the smoke of a furnace, and the people were exceedingly amazed. 19 And the sounds of the trumpet were growing much louder. Moses spoke, and God answered him with a voice. 20 And the Lord came down upon Mount Sinai on the top of the mountain; and the Lord called Moses to the top of the mountain, and Moses went up.
