ἐν ὔμμι κείμεθα, "we are situated" (not, "prostrate") "in your power": ἐν ὔμμι, penes vos, cp. 392, 422, 1443, O. T. 314 (n.), Dem. De Cor. § 193 “ἐν γὰρ τῷ θεῷ τοῦτο τὸ τέλος ἦν, οὐκ ἐν ἐμοί”. The epic forms ὔμμες (nom.), ὔμμι (dat.), ὔμμε (acc.), freq. in Hom., belonged esp. to the Lesbian Aeolic: the acc. occurs in Aesch. Eum. 620 “βουλῇ πιφαύσκω δ᾽ ὔμμ᾽ ἐπισπέσθαι πατρός”: Soph. Ant. 846 “ξυμμάρτυρας ὔμμ᾽ ἐπικτῶμαι.” ἐν ὑμῖν γὰρ (MSS.) is unmetrical: and if γὰρ is omitted, ὑμῖν still mars the metre, which requires a dactyl. κείμεθα, of a critical situation, as
(when his fate is thus trembling in the balance). Cp. 1510.
