| Geneva Study Bible For in much wisdom is much {m} grief: and he that increaseth knowledge increaseth sorrow. (m) Wisdom and knowledge cannot be come by without great pain of body and mind: for when a man has attained the highest, yet is his mind never fully content: therefore in this world is no true happiness. Wesley's Notes 1:18 Grief - Or, displeasure within himself, and against his present condition. Sorrow - Which he does many ways, because he gets his knowledge with hard and wearisome labour, both of mind and body, with the consumption of his spirits, and shortening of his life; because he is often deceived with knowledge falsely so called, and often mistakes error for truth, and is perplexed with manifold doubts, from which ignorant men are wholly free; because he hath the clearer prospect into, and quicker sense of his own ignorance, and infirmities, and disorders, and withal how vain and ineffectual all his knowledge is for the prevention or removal of them; and because his knowledge is very imperfect and unsatisfying, yet increasing his thirst after more knowledge; lastly, because his knowledge quickly fades and dies with him, and then leaves him in no better, and possibly in a much worse condition than the meanest and most unlearned man in the world. Jamieson-Fausset-Brown Bible Commentary 18. wisdom . knowledge-not in general, for wisdom, &c., are most excellent in their place; but speculative knowledge of man's ways (Ec 1:13, 17), which, the farther it goes, gives one the more pain to find how "crooked" and "wanting" they are (Ec 1:15; 12:12). Matthew Henry's Concise Commentary 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. |
