TSK · Ecclesiastes 2:15

behold, I have done according to your word. Behold, I have given you a wise and an understanding heart; so that there has been none like you before you, neither after you shall any arise like you.

I have seen all the works that are done under the sun; and behold, all is vanity and a chasing after wind.

For in much wisdom is much grief; and he who increases knowledge increases sorrow.

For what advantage has the wise more than the fool? What has the poor man, that knows how to walk before the living?
