Job 37:21

21. cleanseth--that is, cleareth the air of clouds. When the "bright light" of the sun, previously not seen through "clouds," suddenly shines out from behind them, owing to the wind clearing them away, the effect is dazzling to the eye; so if God's majesty, now hidden, were suddenly revealed in all its brightness, it would spread darkness over Job's eyes, anxious as he is for it (compare, see on Job 37:19) [Umbreit]. It is because now man sees not the bright sunlight (God's dazzling majesty), owing to the intervening "clouds" (Job 26:9), that they dare to wish to "speak" before God (Job 37:20). Prelude to God's appearance (Job 38:1). The words also hold true in a sense not intended by Elihu, but perhaps included by the Holy Ghost. Job and other sufferers cannot see the light of God's countenance through the clouds of trial: but the wind will soon clear them off, and God shall appear again: let them but wait patiently, for He still shines, though for a time they see Him not (see on Job 37:23).

Verse 21 And now men see not the bright light - Mr. Good gives the sense clearer: - "Even now we cannot look at the light When it is resplendent in the heavens. And a wind from the north hath passed along and cleared them." Elihu seems to refer to the insufferable brightness of the sun. Can any man look at the sun shining in his strength, when a clear and strong wind has purged the sky from clouds and vapours? Much less can any gaze on the majesty of God. Every creature must sink before him. What execrably dangerous folly in man to attempt to arraign His conduct!

Elihu concludes his discourse with some great sayings concerning the glory of God. Light always is, but is not always to be seen. When clouds come between, the sun is darkened in the clear day. The light of God's favour shines ever towards his faithful servants, though it be not always seen. Sins are clouds, and often hinder us from seeing that bright light which is in the face of God. Also, as to those thick clouds of sorrow which often darken our minds, the Lord hath a wind which passes and clears them away. What is that wind? It is his Holy Spirit. As the wind dispels and sweeps away the clouds which are gathered in the air, so the Spirit of God clears our souls from the clouds and fogs of ignorance and unbelief, of sin and lust. From all these clouds the Holy Spirit of God frees us in the work of regeneration. And from all the clouds which trouble our consciences, the Holy Spirit sets us free in the work of consolation. Now that God is about to speak, Elihu delivers a few words, as the sum of all his discourse. With God is terrible majesty. Sooner or later all men shall fear him.
