And whatsoever the unclean person toucheth shall be unclean,.... Not the person unclean by sprinkling, or touching the water of purification, but the unclean person spoken of throughout the chapter, that was unclean by touching a dead body, bone, or grave; whatever that man touched, any vessel or thing, that was unclean also; or "whomsoever", any person, man or woman, for it respects both persons and things:

and the soul that toucheth it; that which the unclean person hath touched; or "him", the unclean person, whether the unclean person touched him, or he the unclean person, or touched anything he had touched, he was unclean; denoting the spreading and infectious nature of sin, and how much sin and sinners are to be avoided; see Leviticus 15:4.

And whatsoever the unclean person toucheth shall be unclean; and the soul that toucheth {m} it shall be unclean until even.

(m) That is, unclean.

19:22 The unclean person - Not he who is so only by touching the water of separation, Nu 19:21, but he who is so by the greater sort of uncleanness, which lasted seven days, and which was not removed without the use of this water of purification.

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.
