On another occasion Pilate was made sensible of the inflammable character of the people with whom he had to deal. He had allowed the construction, perhaps only the restoration, of a costly aqueduct to supply the city, but more especially the temple buildings, with pure water. It was built at the instance of the Sanhedrim and the priests, to whom an abundance of water was a prime necessity. In consideration of this fact, as well as of the circumstance that the benefit of the improvement accrued wholly to the Jewish people, it seemed to Pilate no more than just that the expense should be defrayed from moneys in the temple treasury that were set apart for such purposes. There is no evidence that his action was unreasonable or his method of pursuing it offensive; but clamors at once arose against his project, and on occasion of his coming to Jerusalem a tumultuous crowd pressed on him, and insulting epithets were flung at him from the rabble. To still and scatter them soldiers were sent, in ordinary dress, with clubs in their hands, their weapons being concealed, to overawe the malcontents. This failing, and the tumult increasing, the signal of attack was given; the soldiers fell to with a will; blood was shed; innocent and guilty suffered alike. As this occurred on a feast day, near the Prætorium, and not far from the temple itself, it is quite possible that the sacred precincts were disturbed by the uproar, and that the stain of blood touched consecrated pavement. The popular mind, excited and maddened, seized on the occurrence, represented it as a deliberate affront on the part of the governor, and charged him with mingling the blood of innocent people with the sacrifices they were offering to Jehovah. It is not unlikely that the "tower of Siloam" which fell, crushing eighteen citizens, was a part of this very aqueduct wall, and its fall may have been and probably was, regarded as a judgment on the work and on all who countenanced it. That it made a profound impression on the popular imagination appears in the gospel narratives written many years afterwards. Ewald supposes that this accident happened at an early stage of the work, and was a leading cause of the fanatical outbreak that expressed the popular discontent.
