Ecclesiastes 1:15-17

¹⁵Wayward men be amended of hard; and the number of fools is great without end. (The wayward can only be corrected with great difficulty; and the number of fools cannot be counted.)

¹⁶I spake in mine heart, and I said, Lo! I am made great, and I passed in wisdom all men, that were before me in Jerusalem; and my soul saw many things wisely, and I learned. (I said in my heart, Behold! I am made great, and I have surpassed in wisdom all who were before me in Jerusalem; I have seen many things, and I have become wise, yea, I have learned much.)

¹⁷And I gave mine heart, that I should know prudence and doctrine, and errors and folly. And I knew that in these things also was travail and torment of spirit; (And I gave my heart, or I applied my mind, so that I would understand wisdom and doctrine, and errors and foolishness. And I learned that all these things were also empty and futile, like chasing the wind;)
