Moulton & Milligan — Vocabulary of the Greek NT
γογγύζω [page 130]
This familiar LXX and NT word is fairly attested = murmur in the vernacular, as in P Petr II. 9(3) .9 (B.C. 241 39) τὸ πλήρωμα γογγύζει φάμενοι ἀδικεῖσθαι , the gang (of workmen) are murmuring, saying that they are being wronged. In the curious papyrus P Oxy I. 33 iii. 14 (late ii/A.D.), describing an interview between the Emperor (? Marcus Aurelius) and a rebel, a veteran present interposes with the remark, κύριε , κάθῃ , Ῥωμαῖοι γονγύζο [υσ ]ι , Lord, while you are sitting in judgement, the Romans are murmuring. The verb is MGr. Thumb, Hellen. p. 215, discusses this and other alleged Ionic loans to the later Attic and the Κοινή : see under γογγυσμός .
