As you do not know the path of the wind, or how the bones are formed in a mother’s womb, so you cannot understand the work of God, the Maker of all things.
KJV
As thou knowest not what [is] the way of the spirit, [nor] how the bones [do grow] in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
ASV
As thou knowest not what is the way of the wind, nor how the bones do grow in the womb of her that is with child; even so thou knowest not the work of God who doeth all.
