17. And when Moses had led them out to meet God, from the place of the camp, they stood at the base of the mountain.
18. Then all of Mount Sinai was smoking. For the Lord had descended over it with fire, and smoke ascended from it, as from a furnace. And the entire mountain was terrible.
19. And the sound of the trumpet gradually increased to be louder, and extended to be longer. Moses was speaking, and God was answering him.
20. And the Lord descended over Mount Sinai, to the very top of the mountain, and he called Moses to its summit. And when he had ascended there,
21. he said to him: "Descend, and call the people to witness, lest they might be willing to transgress the limits, so as to see the Lord, and a very great multitude of them might perish.
22. Likewise, the priests who approach toward the Lord, let them be sanctified, lest he strike them down."
