But since the man was incurably brutish and full of savageness, and since there was much denunciation of his licentiousness and greed, Pelopidas became harsh and severe with him, whereupon he ran away with his guards. Then Pelopidas, leaving the Thessalians in great security from the tyrant and in concord with one another, set out himself for Macedonia, where Ptolemy was at war with Alexander the king of the Macedonians. For both parties had invited him to come and be arbiter and judge between them, and ally and helper of the one that appeared to be wronged.
