The meaning of the scarlet, cedar, and hyssop is unexplained in the Scriptures. Expositors have wandered in conjectures, leading to no satisfactory conclusions. One result of their use is manifest. To us, devoid of meaning, they more distinctly mark the essential identity of the rites, in which they occupy the same place, and perform the same office. This may have been one design of their use. The essential identity of these rites is altogether consistent with the minute variations in their forms. These had respect to the diversity of circumstances under which they were administered. The inferior dignity of a single person, a leper, as compared with the whole people, explains the acceptance of lambs or birds for his offerings, while bulls and goats were sacrificed for the nation. In the case of ordinary uncleannesses, the circumstances rendered special provision necessary. Sacrifice was lawful only at the sanctuary, which was the figure of the one holy place and altar where Christ ministers in heaven. But death and other causes of uncleanness were occurring everywhere. The ashes of the red heifer were, therefore, provided. They presented sacrificial elements in a form incorruptible and convenient for transportation. They were a most fitting representation of the “incorruptible blood of Christ.” And, as the proper place of the priests was at the sanctuary, and their presence could not be expected on every occasion of uncleanness elsewhere, it was appointed that any clean person might perform the sprinkling. This was, in fact, a mere ministerial sequel to the sacrificial rites, performed by the priest, at the burning of the red heifer. The probability of the circumstances, and intimations from the rabbins, lead to the conclusion that, as the priests multiplied and were released from the necessity of constant attendance at the sanctuary, they were commonly called to sprinkle the water of purifying. In fact, the Talmud indicates that in the later times the administration, when practicable, took place at Jerusalem, by the hands of the priests, with water from the pool of Siloam, which, flowing from beneath the temple, was recognized as a type of the Holy Spirit.[11] Footnote 11: Compare Ezek. xlvii, 2; John ix, 7. “Go wash in the pool of Siloam, which is by interpretation, Sent.” The minute variations traceable in these rites only make it the more clear that essentially, in form, meaning, and office, they were one baptism.
