On the morning of the third day there was thunder and lightning. A thick cloud covered the mountain, a loud trumpet blast was heard, and everyone in camp trembled with fear.
Mount Sinai was covered with smoke because the LORD had come down in a flaming fire. Smoke poured out of the mountain just like a furnace, and the whole mountain shook.
The door to God's temple in heaven was then opened, and the sacred chest could be seen inside the temple. I saw lightning and heard roars of thunder. The earth trembled and huge hailstones fell to the ground.
