12 I, the Teacher, [1] when king over Israel in Jerusalem, 13 applied my mind to seek and to search out by wisdom all that is done under heaven; it is an unhappy business that God has given to human beings to be busy with. 14 I saw all the deeds that are done under the sun; and see, all is vanity and a chasing after wind. [2] 15 What is crooked cannot be made straight, and what is lacking cannot be counted. 16 I said to myself, "I have acquired great wisdom, surpassing all who were over Jerusalem before me; and my mind has had great experience of wisdom and knowledge." 17 And I applied my mind to know wisdom and to know madness and folly. I perceived that this also is but a chasing after wind. [3] 18 For in much wisdom is much vexation, and those who increase knowledge increase sorrow.

Commentary on Ecclesiastes 1:12-18
(Read Ecclesiastes 1:12-18)
Solomon tried all things, and found them vanity. He found his searches after knowledge weariness, not only to the flesh, but to the mind. The more he saw of the works done under the sun, the more he saw their vanity; and the sight often vexed his spirit. He could neither gain that satisfaction to himself, nor do that good to others, which he expected. Even the pursuit of knowledge and wisdom discovered man's wickedness and misery; so that the more he knew, the more he saw cause to lament and mourn. Let us learn to hate and fear sin, the cause of all this vanity and misery; to value Christ; to seek rest in the knowledge, love, and service of the Saviour.
