International Standard Version Just as you do not understand the way of the spirit in the womb of a pregnant mother, so also you do not know what God is doing in everything he makes.
American Standard Version 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.
Young's Literal Translation As thou knowest not what is the way of the spirit, How -- bones in the womb of the full one, So thou knowest not the work of God who maketh the whole.
