19:17 And for an unclean [person] they shall take of the ashes of the burnt heifer of purification for {h} sin, and {i} running water shall be put thereto in a vessel:
(h) Of the red cow burnt for sin.
(i) Water of the fountain or river.
19:17 Running water - Waters flowing from a spring or river, which are the purest. These manifestly signify God's spirit, which is oft compared to water, and by which alone true purification is obtained. Those who promise themselves benefit by the righteousness of Christ, while they submit not to the influence of his spirit, do but deceive themselves; for they cannot be purified by the ashes, otherwise than in the running water.
19:11-22 Why did the law make a corpse a defiling thing? Because death is the wages of sin, which entered into the world by it, and reigns by the power of it. The law could not conquer death, nor abolish it, as the gospel does, by bringing life and immortality to light, and so introducing a better hope. As the ashes of the heifer signified the merit of Christ, so the running water signified the power and grace of the blessed Spirit, who is compared to rivers of living water; and it is by his work that the righteousness of Christ is applied to us for our cleansing. Those who promise themselves benefit by the righteousness of Christ, while they submit not to the grace and influence of the Holy Spirit, do but deceive themselves; we cannot be purified by the ashes, otherwise than in the running water. What use could there be in these appointments, if they do not refer to the doctrines concerning the sacrifice of Christ? But comparing them with the New Testament, the knowledge to be got from them is evident. The true state of fallen man is shown in these institutions. Here we learn the defiling nature of sin, and are warned to avoid evil communications.
