Ecclesiastes 7:23

"All this have I proved by wisdom: I thought, Wise I will become; but it remained far from me." The ב in בּחכמה is, as at Ecc 1:13, that designating the organon, the means of knowledge. Thus he possessed wisdom up to a certain degree, and in part; but his purpose, comprehended in the one word אחכּמה, was to possess it fully and completely; i.e., not merely to be able to record observations and communicate advices, but to adjust the contradictions of life, to expound the mysteries of time and eternity, and generally to solve the most weighty and important questions which perplex men. But this wisdom was for him still in the remote distance. It is the wisdom after which Job, chap. 28, made inquiry in all regions of the world and at all creatures, at last to discover that God has appointed to man only a limited share of wisdom. Koheleth briefly condenses Job 28:12-22 in the words following:

Solomon had hitherto been proving the vanity of the world and its utter insufficiency to make men happy; now here he comes to show the vileness of sin, and its certain tendency to make men miserable; and this, as the former, he proves from his own experience, and it was a dear-bought experience. He is here, more than any where in all this book, putting on the habit of a penitent. He reviews what he had been discoursing of already, and tells us that what he had said was what he knew and was well assured of, and what he resolved to stand by: All this have I proved by wisdom, Ecc 7:23. Now here, I. He owns and laments the deficiencies of his wisdom. He had wisdom enough to see the vanity of the world and to experience that that would not make a portion for a soul. But, when he came to enquire further, he found himself at a loss; his eye was too dim, his line was too short, and, though he discovered this, there were many other things which he could not prove by wisdom. 1. His searches were industrious. God had given him a capacity for knowledge above any; he set up with a great stock of wisdom; he had the largest opportunities of improving himself that ever any man had; and, (1.) He resolved, if it were possible, to gain his point: I said, I will be wise. He earnestly desired it as highly valuable; he fully designed it as that which he looked upon to be attainable; he determined not to sit down short of it, Pro 18:1. Many are not wise because they never said they would be so, being indifferent to it; but Solomon set it up for the mark he aimed at. When he made trial of sensual pleasures, he still thought to acquaint his heart with wisdom (Pro 2:3), and not to be diverted from the pursuits of that; but perhaps he did not find it so easy a thing as he imagined to keep up his…

7:23-25 it didn’t work: The Teacher was not able to find the wisdom that he sought or the reason for things. Such reasons are hidden in the mind of God (3:11; 8:17).
