Ecclesiastes 2:21-23

Young's Literal Translation

²¹ For there is a man whose labour [is] in wisdom, and in knowledge, and in equity, and to a man who hath not laboured therein he giveth it -- his portion! Even this [is] vanity and a great evil.

²² For what hath been to a man by all his labour, and by the thought of his heart that he laboured at under the sun?

²³ For all his days are sorrows, and his travail sadness; even at night his heart hath not lain down; this also [is] vanity.
