Ecclesiastes 2:10-12

Young's Literal Translation

¹⁰ And all that mine eyes asked I kept not back from them; I withheld not my heart from any joy, for my heart rejoiced because of all my labour, and this hath been my portion, from all my labour,

¹¹ and I have looked on all my works that my hands have done, and on the labour that I have laboured to do, and lo, the whole [is] vanity and vexation of spirit, and there is no advantage under the sun!

¹² And I turned to see wisdom, and madness, and folly, but what [is] the man who cometh after the king? that which [is] already -- they have done it!
