The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from King James Bible: the sun is grievous unto me: for all is vanity and vexation of spirit.
ECC 2:18 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.
ECC 2:19 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.
ECC 2:20 Therefore I went about to cause my heart to despair of all the
labour which I took under the sun.
ECC 2:21 For there is a man whose labour is in wisdom, and in
knowledge, and in equity; yet to a man that hath not laboured therein
shall he leave it for his portion. This also is vanity and a great evil.
