|Matthew Henry's Concise Commentary|
8:20-22 Bildad here assures Job, that as he was so he should fare; therefore they concluded, that as he fared so he was. God will not cast away an upright man; he may be cast down for a time, but he shall not be cast away for ever. Sin brings ruin on persons and families. Yet to argue, that Job was an ungodly, wicked man, was unjust and uncharitable. The mistake in these reasonings arose from Job's friends not distinguishing between the present state of trial and discipline, and the future state of final judgment. May we choose the portion, possess the confidence, bear the cross, and die the death of the righteous; and, in the mean time, be careful neither to wound others by rash judgments, nor to distress ourselves needlessly about the opinions of our fellow-creatures.
Verse 21. - Till he fill thy mouth with laughing, and thy lips with rejoicing. This is very elliptical. The full phrase would be, "God will not cast away a perfect man; therefore, if thou be such, he will not cast away thee, till he fill thy mouth with laughter, and thy lips with rejoicing," or "with shouting for joy."
Gill's Exposition of the Entire Bible
Till he fill thy mouth with laughing, and thy lips with rejoicing. Directing himself to Job; and suggesting, that if he was a perfect, sincere, and upright man. God would not cast him away utterly, but help him out of his present circumstances, and restore him to prosperity; and not leave him until he had filled his heart with so much joy, that his mouth and lips, being also full of it, should break forth in strong expressions of it, and in the most exulting strains, as if it was a time of jubilee with him; see Psalm 126:2; but Bildad tacitly insinuates that Job was not a perfect and good man but an evil doer, whom God had cast away and would not help; and this he concluded from the distressed circumstances he was now in; which was no rule of judgment, and a very unfair way of reasoning, since love and hatred are not to be known by outward prosperity and adversity, Ecclesiastes 9:1. Bar Tzemach interprets "laughing" as at his own goodness, and "rejoicing" as at the evil of the wicked.
Jamieson-Fausset-Brown Bible Commentary
21. Till—literally, "to the point that"; God's blessing on thee, when repentant, will go on increasing to the point that, or until, &c.
