17 then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.
17
then I saw all that God has done. No one can comprehend what goes on under the sun. Despite all their efforts to search it out, no one can discover its meaning. Even if the wise claim they know, they cannot really comprehend it.
