Ecclesiastes 11:5-6

5As you do not know the path of the wind, or how the body is formed Or know how life (or the spirit) / enters the body being formed in a mother’s womb, so you cannot understand the work of God, the Maker of all things.

6Sow your seed in the morning, and at evening let your hands not be idle, for you do not know which will succeed, whether this or that, or whether both will do equally well.
