Ecclesiastes 2:7-17

7 I bought male and female slaves, and had slaves who were born in my house; I also had great possessions of herds and flocks, more than any who had been before me in Jerusalem.
8 I also gathered for myself silver and gold and the treasure of kings and of the provinces; I got singers, both men and women, and delights of the flesh, and many concubines.
9 So I became great and surpassed all who were before me in Jerusalem; also my wisdom remained with me.
10 Whatever my eyes desired I did not keep from them; I kept my heart from no pleasure, for my heart found pleasure in all my toil, and this was my reward for all my toil.
11 Then I considered all that my hands had done and the toil I had spent in doing it, and again, all was vanity and a chasing after wind, and there was nothing to be gained under the sun.
12 So I turned to consider wisdom and madness and folly; for what can the one do who comes after the king? Only what has already been done.
13 Then I saw that wisdom excels folly as light excels darkness.
14 The wise have eyes in their head, but fools walk in darkness. Yet I perceived that the same fate befalls all of them.
15 Then I said to myself, "What happens to the fool will happen to me also; why then have I been so very wise?" And I said to myself that this also is vanity.
16 For there is no enduring remembrance of the wise or of fools, seeing that in the days to come all will have been long forgotten. How can the wise die just like fools?
17 So I hated life, because what is done under the sun was grievous to me; for all is vanity and a chasing after wind.
