Commentary

KJV Study Commentary
And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.

Sinai becomes a furnace—'altogether smoke' (עָשַׁן כֻּלּוֹ, ashan kullo) means totally enveloped. God 'descended in fire' (יָרַד עָלָיו בָּאֵשׁ, yarad alav ba'esh)—fire manifests consuming holiness. The imagery recalls Egypt's plagues (hail and fire, Exodus 9:24) but now God's fire establishes covenant rather than judgment. The smoke ascends 'like a furnace' (כְּעֶשֶׁן הַכִּבְשָׁן, ke'eshen hakivshan)—perhaps recalling Abraham's covenant vision (Genesis 15:17). The mountain 'quaked greatly' (וַיֶּחֱרַד, vayecherad)—creation itself trembles before Creator. This isn't gentle Jesus meek and mild; this is the consuming fire (Hebrews 12:29) whose holiness terrifies.

Historical & Cultural Context

Some scholars propose volcanic activity at Sinai, but the description exceeds natural phenomena—this is supernatural theophany. The furnace imagery would powerfully speak to Israelites fresh from Egyptian brick kilns—God's refining fire versus Pharaoh's enslaving fire.

Reflection Questions

  1. What does fire as God's mode of manifestation teach about His nature?
  2. How does Sinai's smoking mountain connect to the pillar of cloud/fire that led Israel?
