15Then I said in my heart, “As it happens to the fool, so will it happen even to me; and why was I then more wise?” Then I said in my heart that this also is vanity.
16For of the wise man, even as of the fool, there is no memory forever, since in the days to come all will have been long forgotten. Indeed, the wise man must die just like the fool!
17So I hated life, because the work that is worked under the sun was grievous to me; for all is vanity and a chasing after wind.
18I hated all my labour in which I laboured under the sun, because I must leave it to the man who comes after me.
19Who knows whether he will be a wise man or a fool? Yet he will have rule over all of my labour in which I have laboured, and in which I have shown myself wise under the sun. This also is vanity.
20Therefore I began to cause my heart to despair concerning all the labour in which I had laboured under the sun.
