παραφρονέω [page 491]
With 2Co_11:18 παραφρονῶν λαλῶ , I am talking like a madman, we may compare the account, written at earliest about A.D. 200, of the trial of an Alexandrian gymnasiarch before the Emperor Claudius, Chrest. I. 14 iii. 14 , where the condemned man scornfully asks τοί (= τί ) γὰρ ἄλλο ἔχομεν εἲ (= ἢ )παρα [φ ]ρονοῦντι βασιλεῖ τόπον διδόναι ; for what else is there to do except to give way to a mad king? Παραφροσύνη is similarly attributed to the Emperor Gaius Caligula in Jos. Antt. XIX. 284 (v. 2) τοῦ διὰ τὴν πολλὴν ἀπόνοιαν καὶ παραφροσύνην , ὅτι μὴ παραβῆναι ἠθέλησεν τὸ Ἰουδαίων ἔθνος τὴν πάτριον θρησκείαν καὶ θεὸν προσαγορεύειν αὐτόν , ταπεινώσαντος αὐτούς .
