| Matthew Henry's Concise Commentary 15:1-33 Laws concerning ceremonial uncleanness. - We need not be curious in explaining these laws; but have reason to be thankful that we need fear no defilement, except that of sin, nor need ceremonial and burdensome purifications. These laws remind us that God sees all things, even those which escape the notice of men. The great gospel duties of faith and repentance are here signified, and the great gospel privileges of the application of Christ's blood to our souls for our justification, and his grace for our sanctification.
Pulpit CommentaryVerse 31. - That they die not in their uncleanness, when they defile my tabernacle that is among them. The main purpose in the laws of uncleanness is to keep first God's house and then God's people free from the danger of defilement by foul things presenting themselves freely before him and among them. These foul things, symbolizing sinful things, create a ceremonial defilement symbolizing moral defilement.
Gill's Exposition of the Entire BibleThus shall ye separate the children of Israel from their uncleanness,.... Or because of it, and while they are in it, as from other persons, even their nearest relations, and from the house of God, as the next clause shows; or teach them, by observing the above laws and rules, to separate themselves, and that they be careful and cautions to keep themselves apart while in such impurities; and the children of Israel are only made mention of, because these laws are only binding upon them, with their proselytes and servants, free or not free (l), but not upon Gentiles; See Gill on Leviticus 15:2, that they die not in their uncleanness, when they defile my tabernacle that is among them; from whence it appears, that men and women, in the above circumstances, might not go into the tabernacle; and it was chiefly to prevent their access to it that these laws were given, for the greater reverence and honour of it; and that for such persons to enter there was a pollution of it, and the punishment was cutting off, or death; and for one to die in his impurity, without purification and sacrifice, was a dreadful thing, and to be deprecated, and to be guarded against by an observance of the above laws. But the Jews now say (m), that forasmuch as the reason of these precepts was, because such persons were forbidden to enter into the temple, that being destroyed, all these precepts of uncleanness are ceased also.

Jamieson-Fausset-Brown Bible Commentary31-33. Thus shall ye separate the children of Israel from their uncleanness—The divine wisdom was manifested in inspiring the Israelites with a profound reverence for holy things; and nothing was more suited to this purpose than to debar from the tabernacle all who were polluted by any kind of uncleanness, ceremonial as well as natural, mental as well as physical. The better to mark out that people as His family, His servants and priests, dwelling in the camp as in a holy place, consecrated by His presence and His tabernacle, He required of them complete purity, and did not allow them to come before Him when defiled, even by involuntary or secret impurities, as a want of respect due to His majesty. And when we bear in mind that God was training a people to live in His presence in some measure as priests devoted to His service, we shall not consider these rules for the maintenance of personal purity either too stringent or too minute (1Th 4:4).
