Moulton & Milligan — Vocabulary of the Greek NT
συνθρύπτω. According to Hobart p. 249 θρύπτω is a medical term for the crushing of a calculus, and he thinks that the comp%, may have been similarly employed, and, in pursuance of his theme, points out that it is peculiar to Luke (Ac 2113) among Greek authors. But LS® cite at least one other passage, Theod. Prodr. 4. 325 συνεθρύβη. For the simplex θρύπτω see P Oxy III. 471°° (ii/a. pd.) εὔμορφον kal πλούσιον μειράκιον ἐθρύπτετο, where the editors render, “this handsome and rich youth gave himself airs.
