The wall, which was probably little more than a breastwork, though strong and solid, was completed, together with thirteen external redoubts, in three days,[13] every soldier giving his labour. No attempt seems to have been made by the Jews to prevent or hinder the work. Probably they were too weak to attempt any more sorties. A strict watch was set by the Romans—up to this time the blockade does not seem to have been complete—and no one was allowed to approach the wall. And now the last feeble resource of the Jews, the furtive gathering of roots under the city walls, was denied them; and the sufferings of the besieged became too great for any historian to relate. Titus himself, stoic though he was, and resolute to succeed in spite of any suffering, called God to witness, with tears in his eyes, that this was not his doing. Footnote 13: This alone is sufficient to prove the extent of Titus’s army. An army of thirty thousand would be utterly unable to accomplish such a work in three days. Even the obstinacy of the Jews gave way under these sufferings, and more than one attempt was made to introduce the Romans. Matthias opened a communication with the enemy. He was detected, and, with three sons, was executed. One Judas, the son of Judas, who was in command of a tower in the Upper City, concerted with ten of his men, and invited the Romans to come up and take the tower. Had Titus at once ordered a troop to mount, the Upper City might have been easily taken. But he had been too often deceived by feints, and hesitated. The plot was discovered, and Judas, with his ten fellows, was hurled over the ramparts at the feet of the Romans. It was then that Josephus, whom of all men the besieged hated, was wounded in the head, but not seriously, by a stone. The Jews made a tremendous acclamation at seeing this, and sallied forth for a sortie, in the excess of their joy. Josephus, senseless, was taken up and conveyed away, but the next day reappeared and once more offered the clemency of Titus to those who would come out. The hatred which his countrymen bore to Josephus, as to an apostate, natural enough, shows remarkably the love of justice which in all times has distinguished the Jew. His father and mother were in the city. They were not, till late in the siege, interfered with in any way: and his father was set in prison at last, more, apparently, to vex his son than with any idea of doing him an injury.[14]
