Exodus 19:18-20

Darby(i) 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.
