Ecclesiastes 9:7-12

Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God hath already accepted thy works. Let thy garments be always white; and let not thy head lack oil. 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. I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favor to men of skill; but time and chance happeneth to them all. For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are caught in the snare, even so are the sons of men snared in an evil time, when it falleth suddenly upon them.
