'Untimely' in the Bible

Or as an hidden untimely birth I had not been; as infants which never saw light.

As a snail which melteth, let every one of them pass away: like the untimely birth of a woman, that they may not see the sun.

If a man beget an hundred children, and live many years, so that the days of his years be many, and his soul be not filled with good, and also that he have no burial; I say, that an untimely birth is better than he.

for the miscarriage comes in futility (in vain) and passes into obscurity; and its name is covered in obscurity.
