Now Mount Sinai was wrapped in smoke because the LORD had descended on it in fire. The smoke of it went up like the smoke of a kiln, and the whole mountain trembled greatly.
English Standard Version (ESV)
It's easy to focus on the smoke and trembling as just dramatic signs of God's power, but the text emphasizes it as "the smoke of a furnace." This isn't just any smoke; it's the intense, all-consuming kind, mirroring the purifying, yet terrifying, nature of God's presence and His Law as it's revealed. The shaking mountain isn't just a physical event, but a visceral response to the Almighty's descent, showing how His holiness fundamentally alters the very earth.
