And I gave my heart to seek and to search out by wisdom concerning all which is done under the heavens. It is an evil task God has given to the sons of men, to be afflicted by it.
There is one alone, and there is not a second; and there is not a son or a brother to him; and there is not an end to all his labor; even his eyes are not satisfied with riches; and he says, For whom do I labor, and my soul be without good? This is also vanity; yea, it is an evil task.
And I turned my heart about, to know, and to search out, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, and the foolishness of madness:
All this I have seen. I gave my heart to every work that is done under the sun. There is a time in which a man rules over a man for an evil reason to him.
