Through all these frightful scenes the siege of the inner wall went on. The frantic followers of Simon and John continued to fight with unabated ferocity against their enemies without and their countrymen within the wall, undeterred by the sufferings of their fellow-citizens or the near approach of the avenging swords of the besiegers. It was at this time that the judicial murder of the High Priest, Matthias, took place. He was an inoffensive old man, who had introduced Simon into the city, hoping that he would restrain the violence of John. Simon now accused him of a treacherous correspondence with the enemy.[25] He was put to death along with his sons and several of the Sanhedrin. Titus now built fresh walls on which to plant his engines; but they were undermined or destroyed by fire, and he was compelled to surround the whole city by a vast circumvallation, and then to erect fresh platforms and towers, from which the inner wall, with Antonia and the Temple, might be assailed. After several repulses and severe fighting, this was accomplished. The heights were scaled, Antonia levelled with the ground, and the Temple itself laid open to attack. Struck with horror at the profanation of a place dedicated to the service of God, which must ensue if the strife was continued, Titus offered to permit the Jews to come forth and meet him on any other battle ground, promising in that case himself to keep the Temple inviolate from the step of any enemy. He represented that the daily services had already ceased, and the holy ground had been polluted by human blood. He wished to have no share in such impieties, and would prevent them, if he could. His overtures were contemptuously rejected. The Jews themselves set fire to the western cloister, and so laid bare the space between the remains of the Antonia and the Temple.
