18 I hated all my toil in which I had toiled under the sun, seeing that I must leave it to the man who will come after me; 19 and who knows whether he will be a wise man or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity. 20 So I turned about and gave my heart up to despair over all the toil of my labors under the sun, 21 because sometimes a man who has toiled with wisdom and knowledge and skill must leave all to be enjoyed by a man who did not toil for it. This also is vanity and a great evil. 22 What has a man from all the toil and strain with which he toils beneath the sun? 23 For all his days are full of pain, and his work is a vexation; even in the night his mind does not rest. This also is vanity. 24 There is nothing better for a man than that he should eat and drink, and find enjoyment in his toil. This also, I saw, is from the hand of God; 25 for apart from him who can eat or who can have enjoyment? 26 For to the man who pleases him God gives wisdom and knowledge and joy; but to the sinner he gives the work of gathering and heaping, only to give to one who pleases God. This also is vanity and a striving after wind.

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.
