Ecclesiastes 8:16-17

Wycliffe Bible

¹⁶ And I setted mine heart to know wisdom, and to understand the parting, which is turned in earth. A man is, that by days and nights, taketh not sleep with his eyes. (And I set my heart to know wisdom, and to understand what is done on the earth. And in trying to understand this, a person might not close his eyes in sleep for many days and nights.)

¹⁷ And I understood, that of all the works of God, a man may find no reason of those things, that be done under the sun (And I understood, that of all the works of God, a person can find no reason for those things, that be done under the sun); and inasmuch as he travaileth more to seek (it out), by so much (the more) he shall find (it) less; yea, though a wise man say that he knoweth, (or understandeth, what is done under the sun,) he shall not be able to find (it out).
