2 Maccabees 5:5-7

New Catholic Bible

⁵ However, when a false rumor began to circulate that Antiochus had died, Jason^[a] commandeered no fewer than a thousand men and launched a surprise attack on the city. When the defenders on the walls were driven back and the city was on the verge of being taken, Menelaus took refuge in the citadel. ⁶ Jason then embarked on a merciless slaughter of his compatriots, failing to comprehend that success against one’s own kindred was the greatest of disasters, but rather imagining that he was winning trophies of victory over enemies, not over his own people. ⁷ However, he failed to seize control of the government. In the end, his treachery only resulted in disgrace for him, and once again he took refuge in the country of the Ammonites.
