Ecclesiastes 11:4-6

Young's Literal Translation

⁴ Whoso is observing the wind soweth not, And whoso is looking on the thick clouds reapeth not.

⁵ As thou knowest not what [is] the way of the spirit, How -- bones in the womb of the full one, So thou knowest not the work of God who maketh the whole.

⁶ In the morning sow thy seed, And at even withdraw not thy hand, For thou knowest not which is right, this or that, Or whether both of them alike [are] good.
