'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.

And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
