Ecclesiastes 2:18-19

UKJV(i) 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 knows 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 showed myself wise under the sun. This is also vanity.
