Ecclesiastes 11:1-5

Cast your bread on the surface of the waters, for you will find it after many days.

Divide your portion to seven, or even to eight, for you do not know what misfortune may occur on the earth.

If the clouds are full, they pour out rain on the earth; and whether a tree falls toward the south or toward the north, wherever the tree falls, there it lies.

One who watches the wind will not sow and one who looks at the clouds will not harvest.

Just as you do not know the path of the wind, and how bones are formed in the womb of the pregnant woman, so you do not know the activity of God who makes everything.
