[350] But as to Joseph, the son of Zacharias, and Azarias, whom Judas left generals [of the rest of his forces] at the same time when Simon was in Galilee, fighting against the people of Ptolemais, and Judas himself, and his brother Jonathan, were in the land of Gilead, did these men also affect the glory of being courageous generals in war, in order whereto they took the army that was under their command, and came to Jamnia. There Gorgias, the general of the forces of Jamnia, met them; and upon joining battle with him, they lost two thousand of their army, ¹ and fled away, and were pursued to the very borders of Judea. And this misfortune befell them by their disobedience to what injunctions Judas had given them, not to fight with any one before his return. For besides the rest of Judas's sagacious counsels, one may well wonder at this concerning the misfortune that befell the forces commanded by Joseph and Azarias, which he understood would happen, if they broke any of the injunctions he had given them. But Judas and his brethren did not leave off fighting with the Idumeans, but pressed upon them on all sides, and took from them the city of Hebron, and demolished all its fortifications, and set all its towers on fire, and burnt the country of the foreigners, and the city Marissa. They came also to Ashdod, and took it, and laid it waste, and took away a great deal of the spoils and prey that were in it, and returned to Judea.
