Ecclesiastes 8:17

Then, Heb. 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 towards good and bad men, and the reasons of them. A man cannot find out; no man, though never so wise, and inquisitive, and studious, as it follows, 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 these 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.
