Exodus 19:18-20

Revised Geneva Translation

¹⁸ And Mount Sinai was engulfed in smoke, because the LORD came down upon it in fire; and the smoke thereof ascended, as the smoke of a furnace, and all the mount trembled exceedingly.

¹⁹ And when the sound of the trumpet blew long, and waxed louder and louder, Moses spoke. And God answered him by voice.

²⁰ For the LORD came down upon Mount Sinai, on the top of the mount. And when the LORD called Moses up onto the top of the mount, Moses went up.
