Passage 4.26.5
τότε δὲ ἐν Λεύκτροις οἱ Θηβαῖοι νενικηκότες ἀγγέλους ἐς Ἰταλίαν τε καὶ Σικελίαν καὶ παρὰ τοὺς Εὐεσπερίτας ἀπέστελλον, ἔκ τε τῆς ἄλλης, εἴ πού τις Μεσσηνίων εἴη, πανταχόθεν ἀνεκάλουν ἐς Πελοπόννησον. οἱ δὲ θᾶσσον ἢ ὡς ἄν τις ἤλπισε συνελέχθησαν γῆς τε τῆς πατρίδος πόθῳ καὶ διὰ τὸ ἐς Λακεδαιμονίους μῖσος παραμεῖναν ἀεί σφισιν.
Then at this time, after the Thebans had been victorious at Leuctra, they sent messengers to Italy and Sicily, and also to the Euesperitae in Libya. They summoned the Messenians from everywhere—if any were anywhere—to return to the Peloponnese. The Messenians gathered together more swiftly than one might have expected, owing both to longing for their native land and to the hatred toward the Lacedaemonians that had always remained with them.
