Ecclesiastes 1:15

I, the Preacher, was king over Israel in Jerusalem.

I applied my heart to seek and to search out by wisdom concerning all that is done under the sky. It is a heavy burden that God has given to the sons of men to be afflicted with.

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

I said to myself, “Behold, I have obtained for myself great wisdom above all who were before me in Jerusalem. Yes, my heart has had great experience of wisdom and knowledge.”

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.

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