Ecclesiastes 9:5-10

For the living know that they shall die, but the dead do not know any thing; neither do they have any more reward, for their memory is placed into oblivion. Even their love and their hatred and their envy is now perished; neither have they any more a portion in the age in any thing that is done under the sun. Go, eat thy bread with joy and drink thy wine with a joyful heart that thy works might be acceptable unto God. Thy garments shall always be white, and thy head shall never lack ointment. Live joyfully with the wife whom thou dost love all the days which thou art to live in this lake of vanity, which are given unto thee; all the days of thy vanity under the sun: for that is thy portion in this life, and in thy labour in which thou dost work under the sun. Whatever thy hand finds to do, do it with all thy might, for there is no work nor device nor knowledge nor wisdom in Sheol, where thou goest.
