Isn’t it only once that you are going to speak it before the jurors?

Λυσίας τινὶ δίκην ἔχοντι λόγον συγγράψας ἔδωκεν· ὁ δὲ πολλάκις ἀναγνοὺς ἧκε πρὸς τὸν Λυσίαν ἀθυμῶν καὶ λέγων τὸ μὲν πρῶτον αὐτῷ διεξιόντι θαυμαστὸν φανῆναι τὸν λόγον, αὖθις δὲ καὶ τρίτον ἀναλαμβάνοντι παντελῶς ἀμβλὺν καὶ ἄπρακτον· ὁ δὲ Λυσίας γελάσας 'τί οὖν;' εἶπεν 'οὐχ ἅπαξ μέλλεις λέγειν αὐτὸν ἐπὶ τῶν δικαστῶν;' | Lysias once composed a speech for a litigant and gave it to him. The man read it through a number of times and came to Lysias in despair and said that the first time he read it the speech seemed to him wonderfully good, but on taking it up a second and third time it appeared completely dull and ineffectual, "Well," said Lysias laughing, "isn’t it only once that you are going to speak it before the jurors?"
