18 And I hated all my labor wherein I labored under the sun, seeing that I must leave it unto the man that shall be after me. 19 And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity. 20 Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun. 21 For there is a man whose labor is with wisdom, and with knowledge, and with skilfulness; yet to a man that hath not labored therein shall he leave it for his portion. This also is vanity and a great evil. 22 For what hath a man of all his labor, and of the striving of his heart, wherein he laboreth under the sun?

Commentary on Ecclesiastes 2:18-26

(Read Ecclesiastes 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.
