And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this severe burden has God given to the sons of man to be afflicted with.
In the sweat of your face shall you eat bread, till you return unto the ground; for out of it were you taken: for dust you are, and unto dust shall you return.
As you know not what is the way of the wind, nor how the bones do grow in the womb of her that is with child: even so you know not the works of God who makes all.
For God gives to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he gives the work of gathering and heaping up, only that he may give to him that is good before God. This also is vanity and grasping of the wind.
He has made every thing beautiful in its time: also he has put eternity in men’s hearts, so that no man can find out the work that God does from the beginning to the end.
There is one alone, and there is not a second; yea, he has neither child nor brother: yet is there no end of all his labor; neither is his eye satisfied with riches; neither says he, For whom do I labor, and deprive my soul of good? This is also vanity, yea, it is a heavy travail.
I applied my heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:
All this have I seen, and applied my heart unto every work that is done under the sun: there is a time in which one man rules over another to his own hurt.
