[57] In Perea also, Simon, one of the servants to the king, relying upon the handsome appearance and tallness of his body, put a diadem upon his own head also; he also went about with a company of robbers that he had gotten together, and burnt down the royal palace that was at Jericho, and many other costly edifices besides, and procured himself very easily spoils by rapine, as snatching them out of the fire. And he had soon burnt down all the fine edifices, if Gratus, the captain of the foot of the king's party, had not taken the Trachonite archers, and the most warlike of Sebaste, and met the man. His footmen were slain in the battle in abundance; Gratus also cut to pieces Simon himself, as he was flying along a strait valley, when he gave him an oblique stroke upon his neck, as he ran away, and brake it. The royal palaces that were near Jordan at Betharamptha were also burnt down by some other of the seditious that came out of Perea.
