When thou with rebukes - The word here rendered "rebukes" means properly:

(a) proof or demonstration;

(b) confutation or contradiction;

(c) reproof or admonition by words;

(d) reproof by correction or punishment.

This is the meaning here. The idea of the psalmist is, that God, by punishment or calamity, expresses his sense of the evil of human conduct; and that, under such an expression of it, man, being unable to sustain it, melts away or is destroyed.

Dost correct man for iniquity - Dost punish man for his sin; or dost express thy sense of the evil of sin by the calamities which are brought upon him.

Thou makest his beauty - Margin: "That which is to be desired in him." The Hebrew means "desired, delighted in;" then, something desirable, pleasant; a delight. Its meaning is not confined to "beauty." It refers to anything that is to man an object of desire or delight - strength, beauty, possessions, life itself. All are made to fade away before the expressions of the divine displeasure.

To consume away like a moth - Not as a moth is consumed, but as a moth consumes or destroys valuable objects, such as clothing. See the notes at Job 4:19. The beauty, the vigor, the strength of man is marred and destroyed, as the texture of cloth is by the moth.

Surely every man is vanity - That is, he is seen to be vanity - to have no strength, no permanency - by the ease with which God takes away all on which he had prided himself. See the notes at Psalm 39:5.

When thou with rebukes dost correct man - תוכחות tochachoth signifies a vindication of proceedings in a court of law, a legal defense. When God comes to maintain the credit and authority of his law against a sinner, he "causes his beauty to consume away:" a metaphor taken from the case of a culprit, who, by the arguments of counsel, and the unimpeachable evidence of witnesses, has the facts all proved against him, grows pale, looks terrified; his fortitude forsakes him, and he faints in court.

Surely every man is vanity - He is incapable of resistance; he falls before his Maker; and none can deliver him but his Sovereign and Judge, against whom he has offended.

Selah - This is a true saying, an everlasting truth.

When thou with rebukes dost correct man for iniquity,.... The psalmist illustrates his own case, before suggested, by the common case and condition of men, when God corrects them; which he has a right to do, as the Father of spirits, and which he does with rebukes; sometimes with rebukes of wrath, with furious rebukes, rebukes in flames of fire, as the men of the world; and sometimes with rebukes of love, the chastenings of a father, as his own dear children; and always for iniquity, whether one or another; and not the iniquity of Adam is here meant, but personal iniquity: and correction for it is to be understood of some bodily affliction, as the effect of it shows;

thou makest his beauty to consume away like a moth; that is, secretly, suddenly, and at once; as a moth eats a garment, and takes off the beauty of it; or as easily as a moth is crushed between a man's fingers; so the Targum;

"he melts away as a moth, whose body is broken:''

the Vulgate Latin, Septuagint, Ethiopic, and Arabic versions, and so the metaphrase of Apollinarius, read, as a spider which destroys itself. The word rendered "beauty" takes in all that is desirable in man; as his flesh, his strength, his comeliness, his pleasantness of countenance, &c. all which are quickly destroyed by a distemper of the body seizing on it; wherefore the psalmist makes and confirms the conclusion he had made before:

surely every man is vanity; See Gill on Psalm 39:5;

Selah; on this word; see Gill on Psalm 3:2.

When thou with rebukes dost correct man for iniquity, thou {h} makest his {i} beauty to consume away like a moth: surely every man is vanity. Selah.

(h) Though your open plagues do not light on them forever, yet your secret curse continually frets them.

(i) The word signifies all that he desires, as health, force, strength, beauty, and in whatever he has delight, so that the rod of God takes away all that is desired in this world.

39:11 Beauty - His comeliness and all his excellencies or felicities. Moth - As a moth consumeth a garment, to which God compares himself and his judgments, secretly and insensibly consuming a people, Isa 51:8.

his...: Heb. that which is to be desired in him to melt away

11. From his own case, he argues to that of all, that the destruction of man's enjoyments is ascribable to sin.

39:7-13 There is no solid satisfaction to be had in the creature; but it is to be found in the Lord, and in communion with him; to him we should be driven by our disappointments. If the world be nothing but vanity, may God deliver us from having or seeking our portion in it. When creature-confidences fail, it is our comfort that we have a God to go to, a God to trust in. We may see a good God doing all, and ordering all events concerning us; and a good man, for that reason, says nothing against it. He desires the pardoning of his sin, and the preventing of his shame. We must both watch and pray against sin. When under the correcting hand of the Lord, we must look to God himself for relief, not to any other. Our ways and our doings bring us into trouble, and we are beaten with a rod of our own making. What a poor thing is beauty! and what fools are those that are proud of it, when it will certainly, and may quickly, be consumed! The body of man is as a garment to the soul. In this garment sin has lodged a moth, which wears away, first the beauty, then the strength, and finally the substance of its parts. Whoever has watched the progress of a lingering distemper, or the work of time alone, in the human frame, will feel at once the force of this comparison, and that, surely every man is vanity. Afflictions are sent to stir up prayer. If they have that effect, we may hope that God will hear our prayer. The believer expects weariness and ill treatment on his way to heaven; but he shall not stay here long : walking with God by faith, he goes forward on his journey, not diverted from his course, nor cast down by the difficulties he meets. How blessed it is to sit loose from things here below, that while going home to our Father's house, we may use the world as not abusing it! May we always look for that city, whose Builder and Maker is God.
