I devoted myself to study and to explore by wisdom all that is done under heaven.1 What a heavy burden God has laid on men!214
I have seen all the things that are done under the sun; all of them are meaningless, a chasing after the wind.315
What is twisted cannot be straightened;4 what is lacking cannot be counted.
I thought to myself, "Look, I have grown and increased in wisdom more than anyone who has ruled over Jerusalem before me;5 I have experienced much of wisdom and knowledge."
Then I applied myself to the understanding of wisdom,6 and also of madness and folly,7 but I learned that this, too, is a chasing after the wind.
For with much wisdom comes much sorrow;8 the more knowledge, the more grief.9
