Ecclesiastes 9:5-10

For the living know that they will die, but the dead know nothing; and they have no more reward [here], for the memory of them is forgotten. Their love and their hatred and their envy have already perished; neither have they any more a share in anything that is done under the sun. Go your way, eat your bread with joy, and drink your wine with a cheerful heart [if you are righteous, wise, and in the hands of God], for God has already accepted your works. Let your garments be always white [with purity], and let your head not lack [the] oil [of gladness]. Live joyfully with the wife whom you love all the days of your vain life which He has given you under the sun–all the days of futility. For that is your portion in this life and in your work at which you toil under the sun. Whatever your hand finds to do, do it with all your might, for there is no work or device or knowledge or wisdom in Sheol (the place of the dead), where you are going.
