[448] Now Joseph was already slain in Judea, in the manner following: He forgot what charge his brother Herod had given him when he went to Antony; and when he had pitched his camp among the mountains, for Macheras had lent him five regiments, with these he went hastily to Jericho, in :order to reap the corn thereto belonging; and as the Roman regiments were but newly raised, and were unskillful in war, for they were in great part collected out of Syria, he was attacked by the enemy, and caught in those places of difficulty, and was himself slain, as he was fighting bravely, and the whole army was lost, for there were six regiments slain. So when Antigonus had got possession of the dead bodies, he cut off Joseph's head, although Pheroras his brother would have redeemed it at the price of fifty talents. After which defeat, the Galileans revolted from their commanders, and took those of Herod's party, and drowned them in the lake, and a great part of Judea was become seditious; but Macheras fortified the place Gitta [in Samaria].
