One consequence of this policy was, that the inhabitants of the province next to the Egyptian frontier, the Jews, a people formerly submissive even to humility and extremely active and industrious, were driven by systematic religious persecution to open revolt (about 587). The matter came to the senate; and, as it was just at that time with good reason indignant at Demetrius Soter and apprehensive of a combination between the Attalids and Seleucids, while the establishment of a power intermediate between Syria and Egypt was at any rate for the interest of Rome, it made no difficulty in at once recognizing the freedom and autonomy of the insurgent nation (about 593). Nothing, however, was done by Rome for the Jews except what could be done without personal exertion: in spite of the clause of the treaty concluded between the Romans and the Jews which promised Roman aid to the latter in the event of their being attacked, and in spite of the injunction addressed to the kings of Syria and Egypt not to march their troops through Judaea, it was of course entirely left to the Jews themselves to hold their ground against the Syrian kings. The brave and prudent conduct of the insurrection by the heroic family of the Maccabees and the internal dissension in the Syrian empire did more for them than the letters of their powerful allies; during the strife between the Syrian kings Trypho and Demetrius Nicator autonomy and exemption from tribute were formally accorded to the Jews (612); and soon afterwards the head of the Maccabaean house, Simon son of Mattathias, was even formally acknowledged by the nation as well as by the Syrian great-king as high priest and prince of Israel (615).(39) The Parthian Empire
