[102] It was not long after this that an army of those Arabians that lived near to Ethiopia, and of the Philistines, fell upon the kingdom of Jehoram, and spoiled the country and the king's house. Moreover, they slew his sons and his wives: one only of his sons was left him, who escaped the enemy; his name was Ahaziah; after which calamity, he himself fell into that disease which was foretold by the prophet, and lasted a great while, (for God inflicted this punishment upon him in his belly, out of his wrath against him,) and so he died miserably, and saw his own bowels fall out. The people also abused his dead body; I suppose it was because they thought that such his death came upon him by the wrath of God, and that therefore he was not worthy to partake of such a funeral as became kings. Accordingly, they neither buried him in the sepulchers of his fathers, nor vouchsafed him any honors, but buried him like a private man, and this when he had lived forty years, and reigned eight. And the people of Jerusalem delivered the government to his son Ahaziah.
