14. So Moses went down from the mountain to the people and sanctified them [set them apart for God], and they washed their clothes.
15. And he said to the people, Be ready by the day after tomorrow; do not go near a woman.
16. The third morning there were thunders and lightnings, and a thick cloud upon the mountain, and a very loud trumpet blast, so that all the people in the camp trembled.
17. Then Moses brought the people from the camp to meet God, and they stood at the foot of the mountain.
18. Mount Sinai was wrapped in smoke, for the Lord descended upon it in fire; its smoke ascended like that of a furnace, and the whole mountain quaked greatly.
19. As the trumpet blast grew louder and louder, Moses spoke and God answered him with a voice. [Deut. 4:12.]
20. The Lord came down upon Mount Sinai to the top of the mountain, and the Lord called Moses to the top of the mountain, and Moses went up.
21. The Lord said to Moses, Go down and warn the people, lest they break through to the Lord to gaze and many of them perish.
22. And also let the priests, who come near to the Lord, sanctify (set apart) themselves [for God], lest the Lord break forth against them.
