Plato, Laws 915a

ἔνοχος ἔστω, καὶ ἁλοὺς τὴν διπλασίαν τοῦ ἐπιγραφέντος βλάβους τῷ ἀφαιρεθέντι τινέτω. ἀγέτω δὲ καὶ τὸν ἀπελεύθερον, ἐάν τις μὴ θεραπεύῃ τοὺς ἀπελευθερώσαντας ἢ μὴ ἱκανῶς· θεραπεία δὲ φοιτᾶν τρὶς τοῦ μηνὸς τὸν ἀπελευθερωθέντα πρὸς τὴν τοῦ ἀπελευθερώσαντος ἑστίαν, ἐπαγγελλόμενον ὅτι χρὴ δρᾶν τῶν δικαίων καὶ ἅμα δυνατῶν, καὶ περὶ γάμου ποιεῖν ὅτιπερ ἂν συνδοκῇ τῷ γενομένῳ δεσπότῃ. πλουτεῖν δὲ τοῦ ἀπελευθερώσαντος μὴ ἐξεῖναι

he shall be liable for assault, and if convicted he shall pay double his registered due to the man deprived. And a man may arrest also a freedman, if in any case he fails to attend, or to attend sufficiently, on those who have freed him; and such tendance shall consist in the coming of the freedman three times a month to the home of the man that freed him, and there undertaking to do those duties which are both just and feasible, and in regard to marriage also to act as may seem good also to his former master. The freedman shall not be permitted to be more wealthy than the man who freed him;
