Ecclesiastes 11:2-7

²Divide a portion into seven, yea, even into eight; for thou knowest not what evil shall be upon the earth.

³If the clouds be full of rain, they empty themselves upon the earth; and if a tree fall in the south, or in the north, in the place where the tree falleth, there shall it be.

⁴He that observeth the wind shall not sow; and he that regardeth the clouds shall not reap.

⁵As thou knowest not what is the way of the wind, nor how the bones do grow in the womb of her that is with child; even so thou knowest not the work of God who doeth all things.

⁶In the morning sow thy seed, and in the evening withhold not thy hand; for thou knowest not which shall prosper, whether this or that, or whether they both shall be alike good.

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