Ecclesiastes 9:9-10

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. Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, whither thou goest.
