Ecclesiastes 11:3-5

Modern English Version

³ If the clouds are full of rain,
    they empty out on the land;
and if a tree falls to the north or south,
    in the place that the tree falls, there it will be.
⁴ He who observes the wind will not sow,
    and he who regards the clouds will not reap.

⁵ As you do not know the way of the wind,
    or how the bones grow in the womb of her who is with child;
likewise you do not know the work of God
    who has made everything.
