Ecclesiastes 9:9–11

Live joyfully with the wife whom you love all the days of your life of vanity, which he has given you under the sun, all your days of vanity, for that is your portion in life, and in your labor in which you labor under the sun. Whatever your hand finds to do, do it with your might; for there is no work, nor plan, nor knowledge, nor wisdom, in Sheol, where you are going. 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 happen to them all.
