Numbers 19:2

2This is the ordinance of the law. Because it could not but occur that, whilst the faithful were engaged in the world, they should often contract some pollution by their contact with its many impurities, the composition of the water is here described, by the sprinkling of which they might wash away, and expiate their uncleanness: and then certain kinds of pollution are specified, whereof the purification is required. God commands that a red heifer should be slain, which had never been subjected to the yoke; and that it should be burnt without the camp, together with its skin and dung; that the ashes should be gathered by a man that was clean, and laid up without the camp for the common use of the people. But, in order that the water, which was mixed with these ashes, should have the power of reconciliation, God at the same time commands that the blood should be sprinkled seven times before the altar by the finger of the priest. The object of this ceremony was twofold: for God would awaken the attention of the people to reflect more closely upon their impurity; and, although they might be pure within, still would have them carefully look around them, lest they should be polluted from without; and also taught them that, as often as they were infected by any pollution, expiation was to be sought for from elsewhere, viz., from sacrifice and sprinkling; and thus admonish them that men inquire in vain in themselves for the remedies demanded for their purification, because purity can only proceed from the sanctuary. Those, who speculate subtilty on the details, advance some questionable matters. I leave them, therefore, to the enjoyment of their conceits; let it suffice for us to consider generally what God referred to in this ceremony, and what advantage accrued from it to the people. By the red color, they suppose that sin is signified. Meanwhile, lest they should run into a manifest contradiction, they are obliged absurdly to interpret what follows, that He required a heifer perfect and without blemish, as if it were said that there should be no difference of color in her hair; whereas God demands the same thing as in the other sacrifices, which were rejected as faulty if any mark of deformity existed in them. And in this sense it is added that she should never have borne a yoke. Therefore I make no doubt but that God enjoined that a pure heifer, neither mutilated nor lame, should be chosen; and, that her perfectness might be more apparent, as yet unbroken to the yoke. What, then, is the meaning of the red color? First of all, I prefer confessing my ignorance to advancing anything doubtful; but it may be conjectured that a common and ordinary color was rather chosen, lest it should be too conspicuous, as it would have been, if either white or black. But this should be deemed sure, that a perfect heifer, and one free from every blemish, was to be offered, and one too, which had not been broken to bear the yoke by the hands of men, that the purification might have nothing of humanity about it.: But the command to offer her was given to the whole people; because, in order that we may be partakers of ablution, it is necessary that each of us should offer Christ to the Father. For, although He only, and that but once, has offered Himself, still a daily offering of Him, which is effected by faith and prayers, is enjoined to us, not such as (22) the Papists have invented, by whom in their impiety and perverseness, the Lord’s Supper has been mistakenly turned into a sacrifice, because they imagined that Christ must be daily slain, in order that His death might profit us. The offering, however, of faith and prayers, of which I speak, is very different, and by it alone we apply to ourselves the virtue and fruit of Christ’s death.
