12 I the Preacher was king over Israel in Jerusalem. 13 And I applied my heart to seek and to search out by wisdom concerning all that is done under heaven: it is a sore travail that God hath given to the sons of men to be exercised therewith. 14 I have seen all the works that are done under the sun; and, behold, all is vanity and a striving after wind. 15 That which is crooked cannot be made straight; and that which is wanting cannot be numbered. 16 I communed with mine own hear, saying, Lo, I have gotten me great wisdom above all that were before me in Jerusalem; yea, my heart hath had great experience of wisdom and knowledge. 17 And I applied my heart to know wisdom, and to know madness and folly: I perceived that this also was a striving after wind. 18 For in much wisdom is much grief; and he that increaseth knowledge increaseth 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.
