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.
Darby
5 As thou knowest not what is the way of the spirit, how the bones [grow] in the womb of her that is with child, even so thou knowest not the work of God who maketh all.
KJV
5 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.
