'Labored' in the Bible

Thus I hated all the fruit of my labor for which I had labored under the sun, for I must leave it to the man who will come after me.

And who knows whether he will be a wise man or a fool? Yet he will have control over all the fruit of my labor for which I have labored by acting wisely under the sun. This too is vanity.

Therefore I completely despaired of all the fruit of my labor for which I had labored under the sun.

When there is a man who has labored with wisdom, knowledge and skill, then he gives his legacy to one who has not labored with them. This too is vanity and a great evil.

Enjoy life with the woman whom you love all the days of your fleeting life which He has given to you under the sun; for this is your reward in life and in your toil in which you have labored under the sun.
