Passage 3.10.4
τὸ μὲν δὴ χρήματα ἱερὰ δέξασθαι καὶ ἀνδράσιν ἀμῦναι μαντείων πορθήσασι τὸ ἐπιφανέστατον οὐκ ἐς ἔπαινον τίθεμαι, τοσοῦτον δέ οἱ πρόσεστιν ἐς ἔπαινον· Δελφῶν γὰρ τούς τε ἡβῶντας ἀποκτεῖναι καὶ γυναῖκας καὶ τέκνα ἐξανδραποδίσασθαι, καταβαλεῖν δὲ καὶ αὐτὴν ἐς ἔδαφος τὴν πόλιν ἐτόλμων οἱ Φωκεῖς· ταῦτα οὖν μὴ παθεῖν ὑπὸ τῶν Φωκέων αὐτοὺς παρῃτήσατο Ἀρχίδαμος.
That Archidamus received sacred money and aided men who had plundered the most famous of oracles, I do not consider praiseworthy. Yet there is this much in his favor: the Phocians intended to kill all the adult Delphians, enslave their women and children, and raze the city itself to the ground; Archidamus, therefore, persuaded them not to inflict these sufferings upon the Delphians.
