He has made everything right in its time; but he has made their hearts without knowledge, so that man is unable to see the works of God, from the first to the last.
Then I saw all the work of God, and that man may not get knowledge of the work which is done under the sun; because, if a man gives hard work to the search he will not get knowledge, and even if the wise man seems to be coming to the end of his search, still he will be without knowledge.
Where is the wise? where is he who has knowledge of the law? where is the man of this world who has a love of discussion? has not God made foolish the wisdom of this world?
