One practical effect of attaching defilement to a dead body, and to all that touched it, etc., would be to insure early burial, and to correct a practice not uncommon in the East, of leaving the deal to be devoured by the wild beasts.

He that toucheth the dead body of any man shall be unclean seven days - How low does this lay man! He who touched a dead beast was only unclean for one day, Leviticus 11:24, Leviticus 11:27, Leviticus 11:39; but he who touches a dead man is unclean for seven days. This was certainly designed to mark the peculiar impurity of man, and to show his sinfulness - seven times worse than the vilest animal! O thou son of the morning, how art thou fallen!

He that toucheth the dead body of any man,.... A man and not a beast, as Aben Ezra observes; for he that touched the dead body of a beast was unclean only until evening, Leviticus 11:24; any man, Jew or Gentile, as the same writer notes: this is instanced in, as being the principal pollution, though not the only one, yet so some think, for which the water of purification made of the ashes of the burnt heifer was appointed:

shall be unclean seven days; the reason of which is, because death is the fruit of sin, which is of a defiling nature, and to show that all that are dead in sins are defiled and defiling, and are not to be touched, or to have communion and fellowship held with them but to be abstained from.

Whoever touched a corpse, "with regard to all the souls of men," i.e., the corpse of a person, of whatever age or sex, was unclean for seven days, and on the third and seventh day he was to cleanse himself (התחטּא, as in Numbers 8:21) with the water (בּו refers, so far as the sense is concerned, to the water of purification). If he neglected this cleansing, he did not become clean, and he defiled the dwelling of Jehovah (see at Leviticus 15:31). Such a man was to be cut off from Israel (vid., at Genesis 17:14).

He that toucheth the dead body of any man shall be unclean seven days.

man: Heb. soul of man

11-22. He that toucheth the dead body of any man shall be unclean-This law is noticed here to show the uses to which the water of separation [Nu 19:9] was applied. The case of a death is one; and as in every family which sustained a bereavement the members of the household became defiled, so in an immense population, where instances of mortality and other cases of uncleanness would be daily occurring, the water of separation must have been in constant requisition. To afford the necessary supply of the cleansing mixture, the Jewish writers say that a red heifer was sacrificed every year, and that the ashes, mingled with the sprinkling ingredients, were distributed through all the cities and towns of Israel.

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.
