Ecclesiastes 11:5

Among whom none knows what is the way of the wind: as the bones [are hid] in the womb of a pregnant [woman], so thou shalt not know the works of God, [even] all things whatsoever he shall do.

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.

As you don’t know what is the way of the wind, nor how the bones grow in the womb of her who is with child; even so you don’t know the work of God who does all.
