Ecclesiastes 11:5-6
Ecclesiastes 11:5-6 ASV
As 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. In 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.
