Moulton & Milligan — Vocabulary of the Greek NT
κατήγωρ, which in the NT is confined to Rev 1219. occurs in the magical papyrus P Lond 124?° (iv/v A.D.) (=I. p. 122) a charm effective against all 115- ποιεῖ γὰρ πρὸς ἐχθροὺς Kal κατήγορας καὶ λῃστῶν καὶ φόβους καὶ φαντασμοὺς ὀνείρων, “for it works against enemies and accusers and robbers and terrors and dream-spectres”: see Deissmann ZAZ p- 90f., where it is argued that the word is not a Heb. adaptation of κατήγορος (so W Schm Gr. p- 85), but a Greek “*vulgarism,” formed in the same way as ῥήτωρ. Cf. also Thumb Hellen. p. 126, Radermacher Gy. p. 15, Moulton Gy. ii. § 54.
