Ecclesiastes 11:4-6

He who watches the wind will not sow and he who looks at the clouds will not reap. 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 all things. Sow your seed in the morning and do not be idle in the evening, for you do not know whether morning or evening sowing will succeed, or whether both of them alike will be good.
