Ecclesiastes 11:3-5; 10

If clouds are full of water,
they pour rain upon the earth.
Whether a tree falls to the south or the north,
in the place where it falls, there it will lie.
Whoever watches the wind will not plant;
whoever looks at the clouds will not reap.

As you do not know the path of the wind
or how the body is fomed in a mother's womb,
so you cannot understand the work of God,
the maker of all things.

So then banish anxiety from your heart and cast off the troubles of your body for youth and vigor are meaningless...
