Ecclesiastes 2:18 in the World English Bible
I hated all my labor in which I labored under the sun, because I must leave it to the man who comes after me.
Context
17 Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit.
18 Yea, I hated all my labour which I had taken under the sun: because I should leave it unto the man that shall be after me.
19 And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.
