Bede, on Exod 19:18

“And all mount Sinai was on a smoke: because the Lord was come down upon it in fire, and the smoke arose from it as out of a furnace: and all the mount was terrible.”

“When about to give the law, the Lord descended in fire and smoke. Through the brilliance of his manifestation he enlightened the humble, and through the murky smoke of error he dimmed the eyes of the proud.”
