Verse 14. - This is the law. הַתּורָה. By this law the extent of the infection is rigidly defined, as its duration by the last. In a tent. This fixes the date of the law as given in the wilderness, but it leaves in some uncertainty the rule as to settled habitations. The Septuagint, however, has here ἐν οἰκίᾳ, and therefore it would appear that the law was transferred without modification from the tent to the house. In the case of large houses with many inhabitants, some relaxation of the strictness must have been found necessary.

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.This is the law when a man dieth in a tent,.... A tent is only mentioned, because the Israelites now dwelt in tents, as Aben Ezra remarks; otherwise the law holds equally good of an house as of a tent:

all that come into the tent, and all that is in the tent, shall be unclean seven days; the meaning of which is, that all persons that come into a tent or house where a dead body is are equally unclean as those that were in it when it died; and the same is to be supposed of all vessels brought into it, as well as those that are in it, that is, open ones, as appears by what follows.
