Ecclesiastes 11:2-5

²Give a portion to seven, yes, even to eight; for you don’t know what evil will be on the earth.

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

⁴He who observes the wind won’t sow; and he who regards the clouds won’t reap.

⁵As you don’t know what is the way of the wind, nor how the bones grow in the womb of her who is with child; even so you don’t know the work of God who does all.
