καθέδρα, καθέδρας, ἡ (κατά and ἕδρα), a chair, seat: Mat_21:12; Mar_11:15 (Sir_12:12; Herodian, 2, 3, 17 (7 edition, Bekker)); of the exalted seat occupied by men of eminent rank or influence, as teachers and judges: ἐπί τῆς Μωϋσέως καθέδρας ἐκάθισαν, sit on the seat which Moses formerly occupied, i. e. bear themselves as Moses' successors in explaining and defending his law, Mat_23:2. (the Sept. for ξεωΘΡα and ωΖΡαΖϊ. (Xenophon, Aristotle, others.))

καθέδρα kathedra 3x chair, seat, Mat_21:12 ; Mat_23:2 ; Mar_11:15

καθ -έδρα , -ας , ἡ ( < κατά , + ἔδρα , a seat ), [in LXX for H4186 and cogn . forms;] a chair, seat: Mat_21:12 , Mar_11:16 ; of teachers, Mat_23:2 .†

καθέδρα [page 311] καθέδρα is used instead of βῆμα in Ev. Petr. 3, perhaps, as Swete ( ad l. ) suggests, because of its Jewish associations Psa_106:32 [MT Psa_107:32 ], Mat_23:2 ). From the Κοινή we may cite BGU III. 717 .14 (A.D. 149) κόφιν [ος ], καθέδρα , μυροθήκη , πάντα ξύλινα , and the astrological P Ryl II. 63 .10 (iii/A.D.) Σκορπείου καθέδρα , where the word is used = the posterior. For the diminutive καθεδράριον , stool, cf. P Oxy VI. 963 (ii/iii A.D.) χάριν δέ σοι οἶδα , μῆτερ , ἐπὶ τῇ σπουδῇ τοῦ καθεδραρίου , ἐκομισάμην γὰρ αὐτό . Καθέδρα occurs with reference to the sophistical chair occupied by Nicagoras in mid. iii/A.D. in Syll 382 .2 instead of the usual θρόνος (cf. Philostratus Vit. Soph. 618 τὸν Ἀθήνησι τῶν σοφιστῶν θρόνον κατασχών , of Nicagoras). The holder of this chair seems to have ranked above the other professors, cf. Walden Universities of Ancient Greece , p. 94.

καθέδρα καθ-έδρα, ἡ, "a seat", κ. τοῦ λαγῶ a hare's "seat or form", Xen. "the posture of sitting", ἐν τῇ καθέδρᾳ while "they were sitting idle", Thuc.
