Parallel
Ecclesiastes 11:5
Brenton's English Septuagint · Berean Standard Bible
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 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.
