Exodus 19:19 DBY

¹⁷  And Moses brought the people out of the camp to meet with God; and they stood at the foot of the mountain.

¹⁸  And the whole of mount Sinai smoked, because Jehovah descended on it in fire; and its smoke ascended as the smoke of a furnace; and the whole mountain shook greatly.

¹⁹  And the sound of the trumpet increased and became exceeding loud; Moses spoke, and God answered him by a voice.

²⁰  And Jehovah came down on mount Sinai, on the top of the mountain; and Jehovah called Moses to the top of the mountain, and Moses went up.

²¹  And Jehovah said to Moses, Go down, testify to the people that they break not through to Jehovah to gaze, and many of them perish.
