Exodus 19:17-19

Darby Translation

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.
