Ecclesiastes 11:6-8

⁶In the morning sow thy seed, and in the evening withhold not thy hand! For thou knowest not whether this shall prosper, or that, or whether both of them shall be alike good.

⁷Truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun.

⁸Yea, though a man live many years, let him rejoice in them all, and let him think of the days of darkness; for they shall be many. All that cometh is vanity.
