Exodus 19:18-20

EJ2000(i) 18 And all Mount Sinai smoked because the LORD had descended upon it in fire, and its smoke ascended as the smoke of a furnace, and the whole mount quaked greatly. 19 And the voice of the shofar 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.
