The continued tyranny of Tryphon once more raised the hopes of Demetrius, and the Jews resolved to espouse his cause in preference to that of his treacherous enemy. Accordingly Simon sent an embassy offering to acknowledge his supremacy, and to aid him against the usurper. Demetrius received the proposition with alacrity, and in a royal edict formally drawn up and ratified, agreed to recognize Simon as the high-priest and prince of Judæa, to renounce all claims on the Jewish nation for tribute, customs, and taxes, and to grant an amnesty for all past offences against himself. This amounted to a virtual recognition of the complete independence of the country, and the year B.C. 143, in which it was granted, was regarded as the first year of the “freedom of Jerusalem” (1 Macc. xiii. 42). Secure from all immediate danger of foreign interference, Simon now devoted his energies to provide for the internal security of his kingdom. He began by reducing the fortresses that still held out, and garrisoned Gaza, Jamnia, and Joppa. He then turned his attention to the Syrian garrison in the Acra, and reduced it to such straits that the troops composing it were in imminent danger of perishing by famine, and finally agreed to evacuate the fortress on condition that their lives were spared. These terms were accepted, and, to his inexpressible satisfaction, Simon entered the place on the 23rd day of the second month of the year B.C. 142, _with thanksgivings, and branches of palm-trees, and with harps and cymbals, and with viols and hymns and songs_ (1 Macc. xiii. 51). The fortress was then entirely demolished, and the eminence on which it had stood was lowered, until it was reduced below the height of the Temple-hill beside it. This operation cost incredible labour, and occupied upwards of 3 years[46]. The fortifications of the hill, on which the Temple stood, were next strengthened, and a fortress, called Baris[47], was erected to command the site of the Acra, and here Simon and his immediate adherents took up their abode.
