On Is. v. 14, “Hell hath enlarged herself, and opened her mouth without measure,” LXX.  ἐπλάτυνεν ὁ ῾Αδης τὴν φυχὴν αὐτοῦ καὶ διήνοιξε τὸ στόμα αὐτοῦ. it is remarked that these are figurative expressions to denote the multitude of souls that perish.  At the same time an alternative literal meaning is admitted, the mouth being the opening through which the souls of the damned are precipitated into a dark region beneath the earth.
