Read Ecclesiastes 2:11 Using Other Translations
Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
Then I considered all that my hands had done and the toil I had expended in doing it, and behold, all was vanity and a striving after wind, and there was nothing to be gained under the sun.
But as I looked at everything I had worked so hard to accomplish, it was all so meaningless—like chasing the wind. There was nothing really worthwhile anywhere.
