Passage 4.20.1
ἑνδεκάτῳ δὲ ἔτει τῆς πολιορκίας τήν τε Εἶραν ἐπέπρωτο ἁλῶναι καὶ ἀναστάτους γενέσθαι Μεσσηνίους, καὶ δή σφισιν ἐπετέλεσεν ὁ θεὸς Ἀριστομένει καὶ Θεόκλῳ χρησθέν τι. τούτοις γὰρ ἐλθοῦσιν ἐς Δελφοὺς μετὰ τὴν ἐπὶ τῇ τάφρῳ πληγὴν καὶ ἐπερομένοις ὑπὲρ σωτηρίας τοσόνδε εἶπεν ἡ Πυθία· εὖτε τράγος πίνῃσι Νέδης ἑλικόρροον ὕδωρ, οὐκέτι Μεσσήνην ῥύομαι· σχεδόθεν γὰρ ὄλεθρος.
In the eleventh year of the siege, it was fated that Eira should be captured and the Messenians driven from their land. Indeed, the god fulfilled an oracle delivered earlier to Aristomenes and Theoclus. After their defeat at the trench, they traveled to Delphi and consulted the oracle concerning their safety, and the Pythia replied only this: "When a he-goat drinks the winding waters of the Neda, no longer shall I guard Messene, for destruction is near."
