Ecclesiastes 11:3-5

New Catholic Bible

³ When clouds are full of rain,
    they will pour it out upon the earth.
Whether a tree falls to the south or to the north,
    wherever it falls, there will it lie.
⁴ One who continues to watch the wind will never sow,
    and one who keeps staring at the clouds will never reap.
⁵ Just as you do not know the path of the wind
    or how the body is formed in a woman’s womb,
so you do not know the work of God,
    the Creator of all.
