Doth not their excellency which is in them go away? they die, even without {q} wisdom.

(q) That is, before any of them were so wise, as to think of death.

Wesley's Notes

4:21 Excellency - Whatsoever is by common estimation excellent in men, all their natural, and moral, and civil accomplishments, as high birth, great riches, power and wisdom, these are so far from preserving men from perishing, that they perish themselves, together with those houses of clay in which they are lodged. Without wisdom - Even without having attained that only wisdom for which they came into the world. Shall such mean, weak, foolish, sinful, dying creatures as this, pretend to be more just than God, more pure than his maker? No: instead of quarrelling with his afflictions, let him admire that he is out of hell.

Jamieson-Fausset-Brown Bible Commentary

21. their excellency-(Ps 39:11; 146:4; 1Co 13:8). But Umbreit, by an Oriental image from a bow, useless because unstrung: "Their nerve, or string would be torn away." Michaelis, better in accordance with Job 4:19, makes the allusion be to the cords of a tabernacle taken down (Isa 33:20).

they die, even without wisdom-rather, "They would perish, yet not according to wisdom," but according to arbitrary choice, if God were not infinitely wise and holy. The design of the spirit is to show that the continued existence of weak man proves the inconceivable wisdom and holiness of God, which alone save man from ruin [Umbreit]. Bengel shows from Scripture that God's holiness (Hebrew, kadosh) comprehends all His excellencies and attributes. De Wette loses the scope, in explaining it, of the shortness of man's life, contrasted with the angels "before they have attained to wisdom."

Matthew Henry's Concise Commentary

4:12-21 Eliphaz relates a vision. When we are communing with our own hearts, and are still, Ps 4:4, then is a time for the Holy Spirit to commune with us. This vision put him into very great fear. Ever since man sinned, it has been terrible to him to receive communications from Heaven, conscious that he can expect no good tidings thence. Sinful man! shall he pretend to be more just, more pure, than God, who being his Maker, is his Lord and Owner? How dreadful, then, the pride and presumption of man! How great the patience of God! Look upon man in his life. The very foundation of that cottage of clay in which man dwells, is in the dust, and it will sink with its own weight. We stand but upon the dust. Some have a higher heap of dust to stand upon than others but still it is the earth that stays us up, and will shortly swallow us up. Man is soon crushed; or if some lingering distemper, which consumes like a moth, be sent to destroy him, he cannot resist it. Shall such a creature pretend to blame the appointments of God? Look upon man in his death. Life is short, and in a little time men are cut off. Beauty, strength, learning, not only cannot secure them from death, but these things die with them; nor shall their pomp, their wealth, or power, continue after them. Shall a weak, sinful, dying creature, pretend to be more just than God, and more pure than his Maker? No: instead of quarrelling with his afflictions, let him wonder that he is out of hell. Can a man be cleansed without his Maker? Will God justify sinful mortals, and clear them from guilt? or will he do so without their having an interest in the righteousness and gracious help of their promised Redeemer, when angels, once ministering spirits before his throne, receive the just recompence of their sins? Notwithstanding the seeming impunity of men for a short time, though living without God in the world, their doom is as certain as that of the fallen angels, and is continually overtaking them. Yet careless sinners note it so little, that they expect not the change, nor are wise to consider their latter end.
