The circumstances render it certain that this was the form of washing in the expiation of a concealed murder. The elders of the nearest city were required to take an unbroken heifer down into a rough and uncultivated valley or gorge, and there, in the presence of the priests, strike off its head, wash their hands over the carcass, and call God to witness their innocence in the matter. Thus, the water flowing from their hands upon the carcass, transferred to it and the barren spot where it lay the putative guilt of the crime. (Deut. xxi, 3-9.) From this ordinance, the form seems to have become a familiar mode of protesting innocence of crime, and is memorable for that occasion when Pilate “took water and washed his hands before the multitude, saying, I am innocent of the blood of this just person: see ye to it.”—Matt. xxvii, 24. Two primitive representations of this scene, in sculptured relief, have been found in the catacombs at Rome. They date from the first centuries of the Christian era. In them the wife of Pilate appears in the background, with averted face. An attendant holds a vase or pitcher in one hand, and in the other a bowl: while Pilate sits rubbing his hands. The position of the bowl shows it to be empty. “The mode of washing implied in the empty bowl is characteristic. In the east, the water is still poured from the vase over the hands, and caught in the bowl, so that it should not pass over them twice.”[16] Footnote 16: Maitland’s “Church of the Catacombs,” p. 261.
