Moulton & Milligan — Vocabulary of the Greek NT
παρεισέρχομαι, lit. *‘come in from the side.” The use of the verb in Rom 57° ‘*come in to the side of a state of things already existing” (SH) shows that the idea of stea/th is not necessarily present: cf. Vett. Val. p. 357° τοῦτο δέ μοι παρεισῆλθεν περὶ τῆς προκειμένης ἀγωγῆς. On the other hand with Gal 24 ‘*who sneaked in to spy out our freedom” Burton (7CC ad /.) compares such a passage as Luc. Asin. 15 εἰ λύκος παρεισέλθοι. The corr. double compd. παρεξέρχομαι occurs in the late P Lond τοῦ 517 (vii/a.D.) (= III. p. 282) ἵνα μὴ τοῦ λοιπο[ῦ] παρεξέλθῃ τοῦ σκοποῦ ὑμῶν.
