Passage 9.7.1
τότε δὲ τοὺς Θηβαίους γενομένους ἀναστάτους ὑπὸ Ἀλεξάνδρου καὶ διαπεσόντας ἐς Ἀθήνας ὕστερον Κάσσανδρος ὁ Ἀντιπάτρου κατήγαγεν. ἐς δὲ τῶν Θηβῶν τὸν οἰκισμὸν προθυμότατοι μὲν ἐγένοντο Ἀθηναῖοι, συνεπελάβοντο δὲ καὶ Μεσσήνιοι καὶ Ἀρκάδων οἱ Μεγάλην πόλιν ἔχοντες.
At that time the Thebans, having been expelled from their city by Alexander and having fled to Athens, were later restored by Cassander, the son of Antipater. The Athenians showed the greatest eagerness for the rebuilding of Thebes, and the Messenians also contributed assistance, along with the Arcadians who inhabited Megalopolis.
