Labour - Compare Ecclesiastes 2:4-8.

A wise man or a fool? - Alas! Solomon, the wisest of all men, made the worst use of his wisdom, had three hundred wives and seven hundred concubines, and yet left but one son behind him, to possess his estates and his throne, and that one was the silliest of fools!

And who knoweth whether he shall be a wise man or a fool?.... The king that should be after him, as the Targum, that should be his successor and heir; and so whether he would make a good or bad use of what was left; whether he would keep and improve it, or squander it away; suggesting, that could he be sure he would be a wise man that should come into his labours, it would be some satisfaction to him that he had laboured, and such a man should have the benefit of it; but as it was a precarious thing what he would be, he could take no pleasure in reviewing his labours he was about to leave. Some think that Solomon here gives a hint of the suspicion he had, that his son Rehoboam, his successor and heir, would turn out a foolish man, as he did;

yet shall he have rule over all my labour wherein I have laboured, and wherein I have showed myself wise, under the sun; be he what he will, all will come into his hands; and he will have the power of disposing of all at his pleasure; not only of enjoying it, but of changing and altering things; and perhaps greatly for the worse, if he does not entirely destroy what has been wrought with so much care and industry, toil and labour, wisdom and prudence; the thought of all which was afflicting and distressing: and therefore he adds,

This is also vanity; and shows there is no happiness in all that a man does, has, or enjoys; and this circumstance, before related, adds to his vexation and unhappiness.

"And who knoweth whether he shall be wise or foolish? and he will have power over all my labour with which had wearied myself, and had acted wisely, under the sun: this also is vain." או...ה, instead of אם...ה, in the double question, as at Job 16:3. What kind of a man he will be no one can previously know, and yet this person will have free control (cf. שׁלט, p.641) over all the labour that the testator has wisely gained by labour - a hendiadys, for חכם with the obj. accus. is only in such a connection possible: "my labour which I, acting wisely, gained by labour."

In view of this doubtful future of that which was with pains and wisely gained by him, his spirit sank within him.

And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.

2:19 Or a fool - Who will undo all that I have done, and turn the effects of my wisdom into instruments of his folly. Some think he had such an opinion of Rehoboam.

2:18-26 Our hearts are very loth to quit their expectations of great things from the creature; but Solomon came to this at length. The world is a vale of tears, even to those that have much of it. See what fools they are, who make themselves drudges to the world, which affords a man nothing better than subsistence for the body. And the utmost he can attain in this respect is to allow himself a sober, cheerful use thereof, according to his rank and condition. But we must enjoy good in our labour; we must use those things to make us diligent and cheerful in worldly business. And this is the gift of God. Riches are a blessing or a curse to a man, according as he has, or has not, a heart to make a good use of them. To those that are accepted of the Lord, he gives joy and satisfaction in the knowledge and love of him. But to the sinner he allots labour, sorrow, vanity, and vexation, in seeking a worldly portion, which yet afterwards comes into better hands. Let the sinner seriously consider his latter end. To seek a lasting portion in the love of Christ and the blessings it bestows, is the only way to true and satisfying enjoyment even of this present world.
