Ecclesiastes 2:21-23

Darby Translation

²¹ For there is a man whose labour hath been with wisdom, and with knowledge, and with skill, and who leaveth it to a man that hath not laboured therein, to be his portion. This also is vanity and a great evil.

²² For what will man have of all his labour and of the striving of his heart, wherewith he hath wearied himself under the sun?

²³ For all his days are sorrows, and his travail vexation: even in the night his heart taketh no rest. This also is vanity.
