Ecclesiastes 11:5

As thou knowest not what is the way of the spirit, or of the wind, concerning whose various vagaries men are just as puzzled as ever, in spite of the progress made by the science of meteorology, Cf John 3:8, nor how the bones do grow in the womb of her that is with child, in the mystery of creation or generation, Psalms 139:14, even so thou knowest not the works of God, who maketh all, the works of His almighty power are unfathomable by the mind of finite men.
