'Reward' in the Bible

All that my eyes desired I did not refuse them. I did not withhold my heart from any pleasure, for my heart was pleased because of all my labor and this was my reward for all my labor.

Here is what I have seen to be good and fitting: to eat, to drink and enjoy oneself in all one’s labor in which he toils under the sun during the few years of his life which God has given him; for this is his reward.

Furthermore, as for every man to whom God has given riches and wealth, He has also empowered him to eat from them and to receive his reward and rejoice in his labor; this is the gift of God.

For the living know they will die; but the dead do not know anything, nor have they any longer a reward, for their memory is forgotten.

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.
