Passage 8.27.9
Μεγαλοπολίταις δὲ ἐς τὴν Θηβαίων συμμαχίαν ἐγγραφεῖσιν ἀπὸ Λακεδαιμονίων δεῖμα ἦν οὐδέν. ὡς δὲ ἐς τὸν πόλεμον τὸν ἱερὸν ὀνομασθέντα οἱ Θηβαῖοι κατέστησαν καὶ αὐτοῖς ἐπέκειντο οἱ Φωκεῖς, τήν τε ὅμορον τῇ Βοιωτῶν ἔχοντες καὶ ὄντες οὐκ ἀδύνατοι χρήμασιν ἅτε τὸ ἱερὸν τὸ ἐν Δελφοῖς κατειληφότες,
The Megalopolitans, once enrolled in alliance with the Thebans, had nothing more to fear from the Lacedaemonians. But when the Thebans engaged in the so-called Sacred War, the Phocians came to face them as opponents, holding territory bordering on that of Boeotia and proving formidable through the wealth they possessed from having seized the sanctuary at Delphi.
