- οἱ τὰ τοιαῦτα λέγοντες ἢ τὴν ὑπόθεσιν, περὶ ἧς βουλεύεσθαι,
- οὐχὶ τὴν οὖσαν παριστάντες ὑμῖν ἁμαρτάνειν. ἐγὼ δέ, ὅτι μέν
- ποτ᾿ ἐξῆν τῇ πόλει καὶ τὰ αὑτῆς ἔχειν ἀσφαλῶς καὶ Φίλιππον
- τιμωρήσασθαι, καὶ μάλ᾿ ἀκριβῶς οἶδα· ἐπ᾿ ἐμοῦ γάρ, οὐ πάλαι
- γέγονεν ταῦτ᾿ ἀμφότερα· νῦν μέντοι πέπεισμαι τοῦθ᾿ ἱκανὸν
- προλαβεῖν ἡμῖν εἶναι τὴν πρώτην, ὅπως τοὺς συμμάχους
- σώσομεν. ἐὰν γὰρ τοῦτο βεβαίως ὑπάρξῃ, τότε καὶ περὶ τοῦ
- τίνα τιμωρήσεταί τις καὶ ὃν τρόπον ἐξέσται σκοπεῖν· πρὶν δὲ

- ሰው እንደቤቱ እንጅ እንደ ጉረቤቱ አይተዳደርም።
- እግዜር የከፈተውን ጉሮሮ ሳይዘጋው አይድርም።
- የጎረቤት ሌባ፥ ቢያዩት ይስቅ ባያዩት ያጠልቅ።
- ሥራ ከመፍታት ልጄን ላፋታት።
- ዓባይ ማደሪያ የለው፥ ግንድ ይዞ ይዞራል።
- የእስላም አገሩ መካ የአሞራ አገሩ ዋርካ።
