F. A. Paley, Select Private Orations of Demosthenes

χορηγὸν — ἔχουσα ‘Having my father to furnish the means,’ Kennedy. Shilleto quotes this with other examples of the use, on De Fals. Leg. p. 408, § 238. Similarly χορηγεῖν and χορηγία were used of supplies in general, by Aristotle and later writers.—[e.g. Ethics I 10 § 15 τοῖς ἐκτὸς ἀγαθοῖς ἱκανῶς κεχορηγημένον and I 8 § 15 οὐ ῥᾴδιον τὰ καλὰ πράττειν ἀχορήγητον ὄντα (‘without appliances’); also in the Greek Testament, 2 Cor. ix 10, 1 Pet. iv 11, 2 Pet. i 5 and 11. The word λῃτουργία has a similar history. S.]—ὑπὸ, i.e. διὰ τὴν ἐπιθυμίαν.

οὐκ ἴσα ἐμοὶ sc. ἀλλὰ πλείω ἐμοῦ.
