Ecclesiastes 8:17 - Joseph Benson’s Commentary on the Old and New Testaments

Then Hebrew, and, or, moreover, I beheld all the work of God I considered the counsels and ways of God, and the various methods of his providence toward good and bad men, and the reasons of them. That a man cannot find out the work, &c. No man, though ever so wise, is able fully and perfectly to understand these things. And therefore, it is best for man not to perplex himself with endless and fruitless inquiries about those matters, but quietly to submit to God's will and providence, and to live in the fear of God, and the comfortable enjoyment of his blessings.
