χρὴ τῶν ἀγαθῶν διακναιομένων πενθεῖν ὅστις χρηστὸς ἀπ' ἀρχῆς νενόμισται → when a good man is hurt, all who would be called good must suffer with him | when good men are being dragged down, anyone with worthy credentials must feel their pain | when the noble are afflicted, those who all their lives have been deemed loyal must mourn
