Ecclesiastes 11:6-8

⁶In the morning sow your seed, and in the evening let not your hand be slack: for you know not what sort shall prosper, whether this or that, or whether both shall be good alike.

⁷Moreover the light is sweet, and it is good for the eyes to see the sun.

⁸For even if a man should live many years, and rejoice in them all; yet let him remember the days of darkness; for they shall be many. All that comes is vanity.
