then I beheld all the work of God, that man cannot find out the work that is done under the sun; because though a man labour to seek it out, yet he shall not find it; yea further, though a wise man think to know it, yet shall he not be able to find it.
Aramaic Targum to Ecclesiastes
And I saw every mighty work of the Lord, for it is awful; and man cannot find out the mighty work of the Lord which is done in this world under the sun; when man labours to seek what will be, he shall not find it; and even if a wise man says by his word, that he will know what will be at the end of days, he cannot find it.
