Êxodo 19:18

18 Mount Sinai was covered with smoke, because the Lord descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountain Most Hebrew manuscripts; a few Hebrew manuscripts and Septuagint [and all the people] trembled violently.

18 And mount Sinai, the whole of it, smoked, because Jehovah descended upon it in fire; and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.
