Ecclesiastes 11:4-6

11:4 He who watches the wind will not sow,

and he who observes the clouds will not reap.

11:5 Just as you do not know the path of the wind,

or how the bones form in the womb of a pregnant woman,

so you do not know the work of God who makes everything.

11:6 Sow your seed in the morning,

and do not stop working until the evening;

for you do not know which activity will succeed –

whether this one or that one, or whether both will prosper equally.
