Passage 7.9.2
τούτων δὲ πλείονα ἐνεκάλουν Ἀχαιοῖς Ἀρεὺς καὶ Ἀλκιβιάδας, ὡς Λακεδαιμόνιοι μὲν καὶ δόκιμοι τὰ μάλιστα ἐν τῇ Σπάρτῃ, τὰ δὲ ἐς Ἀχαιοὺς οὐ δίκαιοι· γενομένους γὰρ ὑπὸ Νάβιδος φυγάδας ὑπεδέξαντο αὐτοὺς οἱ Ἀχαιοὶ καὶ ἀποθανόντος Νάβιδος παρὰ γνώμην Λακεδαιμονίων τοῦ δήμου κατάγουσιν ἐς Σπάρτην. τότε οὖν ἀναβεβηκότες καὶ οὗτοι παρὰ τὴν βουλὴν προθυμότατα ἐνέκειντο Ἀχαιοῖς· Ἀχαιοὶ δέ σφισιν ἀπελθοῦσιν ἐπιβάλλουσιν ἐν τῷ συνεδρίῳ θάνατον ζημίαν.
Areus and Alcibiades brought many charges against the Achaeans, asserting that although they were Spartans and particularly distinguished among the citizens in Sparta, they had been treated unjustly by the Achaeans. For when these men had become exiles due to Nabis, the Achaeans had received them and, upon the death of Nabis, had restored the common people to Sparta against the wishes of the Lacedaemonians. Therefore, once returned and having secured high positions contrary to the will of the council, they pursued their enmity against the Achaeans most zealously. The Achaeans, however, after they had departed, sentenced them in an assembly to the penalty of death.
