What profit hath man of all his labor wherein he laboreth under the sun?

And I hated all my labor wherein I labored under the sun, seeing that I must leave it unto the man that shall be after me.

And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity.

Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun.

For what hath a man of all his labor, and of the striving of his heart, wherein he laboreth under the sun?

What profit hath he that worketh in that wherein he laboreth?

Behold, that which I have seen to be good and to be comely is for one to eat and to drink, and to enjoy good in all his labor, wherein he laboreth under the sun, all the days of his life which God hath given him: for this is his portion.

All this have I seen, and applied my heart unto every work that is done under the sun: there is a time wherein one man hath power over another to his hurt.

Live joyfully with the wife whom thou lovest all the days of thy life of vanity, which he hath given thee under the sun, all thy days of vanity: for that is thy portion in life, and in thy labor wherein thou laborest under the sun.

If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
