Mount Sinai was covered with smoke, because the Lord came down on it in fire. The smoke rose from the mountain like smoke from a furnace, and the whole mountain shook wildly.
When the people heard the thunder and the trumpet, and when they saw the lightning and the smoke rising from the mountain, they shook with fear and stood far away from the mountain.
He stands and shakes the earth. He looks, and the nations shake with fear. The mountains, which stood for ages, break into pieces; the old hills fall down. God has always done this.
