Either,
1. The wrath of God; or rather,
2. A man's own wrath, fretting, and impatience, and indignation; which kills men, partly, naturally, as it preys upon a man's spirit, and wasteth him inwardly, and so hastens his death, of which see Proverbs 14:30, Proverbs 17:22; partly, morally, as it prompts him to those rash, and furious, and wicked actions which may procure his death; and partly, meritoriously, as it provoketh God to cut him off, and to bring upon him those further and severe strokes which he mentions in the following words. The foolish man; either,
1. The rash and inconsiderate man, who doth not ponder things impartially; but, like a man mad, rageth against God, and torments himself and all that hear him. Or,
2. The ungodly man, who is frequently called a fool in Scripture language, and who is here opposed to the saints, Job 5:1. Envy: he taxeth Job, who spoke with great envy at those that were never born, or were in their graves, Job 3:10,12, &c. The silly one; properly, the man who, for want of true wisdom, is soon deceived with false opinions, and appearances, and present things; which is thy case, O Job. The sense of the verse may be this, I perceive, O Job, that thou art full of envy at wicked men, who at present are, or seem to be, in a happier condition than thou; and of wrath against God, who denies thee that mercy, and loads thee with afflictions; and this shows thee to be a foolish and weak man. For those men, notwithstanding their present prosperity, are doomed to great and certain misery, as it here follows. And so this verse coheres with the following as well as the foregoing verses.
