Job 39:4

Their young ones are in good liking,.... Plump, fat, and sleek, as fawns are:they grow up with corn; by which they grow, or without in the field, as the word also signifies; and their growth and increase is very quick, as Aristotle observes ;they go forth, and return not unto them: they go forth into the fields, and shift and provide for themselves, and trouble their dams no more; and return not to them, nor are they known by them.
