Ecclesiastes 11:2; Ecclesiastes 11:5-6; Ecclesiastes 11:8-9
Give a portion to seven, and also to eight; for thou knowest not what evil shall be upon the earth.
As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
In the morning sow thy seed, and in the evening withhold not thine hand: for thou knowest not whether shall prosper , either this or that, or whether they both shall be alike good.
But if a man live many years, and rejoice in them all; yet let him remember the days of darkness; for they shall be many . All that cometh is vanity.
Rejoice , O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these things God will bring thee into judgment.
