Yet he passed away - Compare the notes at Job 20:5. The allusion here, of course, is to the man, and not to the tree, though the grammatical construction might refer to either. The idea is that he passed out of view - "he was gone;" he had no permanent abode on earth, but with all his pomp and splendor he had disappeared. Neither his prosperity, his greatness, nor his wealth, could secure him a permanent abode on earth. It might be said, also, in reply to this, that the good man passes away and is not. That is true. But the meaning here is, that this occurs "so much more frequently" in the case of a wicked man, or that wickedness is followed so often in this life by the judgment of God in cutting him off, as to show that there is a moral government, and that that government is administered in favor of the righteous, or that it is an advantage in this life to be righteous. It cannot be meant that this is "universally" so here, but that this is the "general" rule, and that it is so constant as to show that God is on the side of virtue and religion.
And lo, he was not - He was no more; there was no longer any such person: The word "lo" implies that there was some degree of surprise, or that what had occurred was not looked for or expected. The observer had seen him in great power, flourishing, rich, honored; and, to his astonishment, he soon passed entirely away.
Yea, I sought him, but he could not be found - This is intended to "confirm" what had been just said, or to show how completely he had disappeared. It might be supposed, perhaps, that his removal was only temporary - that he was still somewhere upon the earth; but the psalmist says that after the most diligent search, he could not find him. He had disappeared entirely from among men.

Yet he passed away - Both Nebuchadnezzar and his wicked successor, Belshazzar; and on the destruction of the latter, when God had weighed him in the balance, and found him wanting, numbered his days, and consigned him to death, his kingdom was delivered to the Medes and Persians; and thus the Babylonian empire was destroyed.

Yet he (x) passed away, and, lo, he [was] not: yea, I sought him, but he could not be found.
(x) So that the prosperity of the wicked is but as a cloud, which vanishes away in a moment.

Yet he passed away,.... At once, on a sudden; either his riches and honour, which, in one hour, came to nought, by one providence or another; or he himself by death; in the midst of all his prosperity, and while blessing himself in it, his soul was required of him; and so the Targum is, "he ceased from the world"; he went out of it unawares: the laurel, or bay tree, very quickly grows old (d);
and, lo, he was not; he was not reduced to nothing; he did not become a nonentity, though he might wish himself to be so; it being better for him if he had never been born; but he was not in the land of the living, in hell he lifted up his eyes;
yea, I sought him, but he could not be found; in the place where he formerly was, that knowing him no more; he could not be found on earth, from whence he was gone; nor in heaven, where no place is found for such wicked men; he was gone to his own place, as is said of Judas, and of whom Jerom interprets the whole of this passage.
(d) "Senescit velociter", Plin. Nat. Hist. l. 16. c. 44.

he was not--(Compare Psalm 37:10).

Yet - He was gone in an instant. But - There was no monument or remainder of him left.
