Ecclesiastes 11:3-5

New Century Version

³ If clouds are full of rain,
    they will shower on the earth.
A tree can fall to the north or south,
    but it will stay where it falls.
⁴ Those who wait for perfect weather
    will never plant seeds;
those who look at every cloud
    will never harvest crops.

⁵ You don’t know where the wind will blow,
    and you don’t know how a baby grows inside the mother.
In the same way, you don’t know what God is doing,
    or how he created everything.
