However, John stayed behind, out of his fear of Simon, even while his own men were earnest in making a sally upon their enemies without. Yet did not Simon lie still, for he lay near the place of the siege; he brought his engines of war and disposed of them at due distances upon the wall, both those which they took from Cestius formerly, and those which they got when they seized the garrison that lay in the tower Antonia. But though they had these engines in their possession, they had so little skill in using them that they were in great measure useless to them; but a few there were who had been taught by deserters how to use them, which they did use, though after an awkward manner. So they cast stones and arrows at those that were making the banks; they also ran out upon them by companies and fought with them. Now those that were at work covered themselves with hurdles spread over their banks, and their engines were opposed to them when they made their excursions. The engines, that all the legions had ready prepared for them, were admirably contrived; but still more extraordinary ones belonged to the Tenth legion: those that threw darts and those that threw stones were more forcible and larger than the rest, by which they not only repelled the excursions of the Jews, but drove those away that were upon the walls also. Now the stones that were cast were of the weight of a talent, and were carried two furlongs and farther. The blow they gave was no way to be sustained, not only by those that stood first in the way, but by those that were beyond them for a great space. As for the Jews, they at first watched the coming of the stone, for it was of a white color, and could therefore not only be perceived by the great noise it made, but could be seen also before it came, by its brightness. Accordingly, the watchmen that sat upon the towers gave them notice when the engine was let go, and the stone came from it, and cried out aloud, in their own country language, "The son cometh!" so those that were in its way stood off, and threw themselves down upon the ground; by which means, and by their thus guarding themselves, the stone fell down and did them no harm. But the Romans contrived how to prevent that, by blacking the stone, who then could aim at them with success when the stone was not discerned beforehand as it had been till then; and so they destroyed many of them at one blow. Yet did not the Jews, under all this distress, permit the Romans to raise their banks in quiet, but they shrewdly and boldly exerted themselves, and repelled them both by night and by day.
