Ecclesiastes 11:3-5

World English Bible

³ If 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.
⁴ He who observes the wind won’t sow;
    and he who regards the clouds won’t reap.
⁵ As 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.
