[18] And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly. [19] And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice. [20] And the LORD came down upon mount Sinai, on the top of the mount: and the LORD called Moses up to the top of the mount; and Moses went up. [21] And the LORD said unto Moses, Go down, charge the people, lest they break through unto the LORD to gaze, and many of them perish. [22] And let the priests also, which come near to the LORD, sanctify themselves, lest the LORD break forth upon them. [23] And Moses said unto the LORD, The people cannot come up to mount Sinai: for thou chargedst us, saying, Set bounds about the mount, and sanctify it. [24] And the LORD said get thee down, and thou shalt come up, thou, and Aaron with thee: but let not the priests and the people break through to come up unto the LORD, lest he break forth upon them. [25] So Moses went down unto the people, and spake unto them.
