Ecclesiastes 11:6-10

⁶In the morning sow thy seed, and in the evening let not thy hand rest; for thou knowest not which will succeed, whether this or that, or whether both of them will be alike good.

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

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

⁹Rejoice, O young man, in thy childhood; and let thy heart cheer thee in the days of thy youthful vigor, and walk firmly in the ways of thy heart, and in the direction which thy eyes see: but know thou, that concerning all these things God will bring thee into judgment.

¹⁰And remove vexation from thy heart, and cause evil to pass away from thy body; for childhood and the time when the head is black are vanity.
