Exodus 19:18-20

TKJU(i) 18 And Mount Sinai was altogether raging smoke, because the LORD descended upon it in fire: And its smoke ascended as the smoke of a furnace, and the whole mount quaked greatly. 19 And when the sound of the trumpet sounded long, and waxed louder and louder, Moses spoke, 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.
