This solemn admonition is addressed to Moses and Aaron, see Leviticus 15:1.

Leviticus 15:31

My tabernacle - Strictly, "my dwelling-place" משׁכן mı̂shkān, as in Leviticus 8:10; Leviticus 17:4; Leviticus 26:11. The word rendered "tabernacle" elsewhere in Leviticus is properly "tent." See the Exodus 26:1 note.

Thus shall ye separate the children of Israel from their uncleanness - By this separation the cause became less frequent, and the contagion, if it did exist, was prevented from spreading. So pest-houses and fever-wards are constructed for the purpose of separating the infected from the sound; and thus contagion is lessened, and its diffusion prevented.

That they die not - That life may be prolonged by these prudential cares; and that he who is morally and legally unclean, may not presume to enter into the tabernacle of God till purified, lest he provoke Divine justice to consume him, while attempting to worship with a polluted mind and impure hands.

1. How unpromising and how forbidding, at the first view, is this chapter! and yet how full of wise, humane, and moral regulations, manifesting at once the wisdom and kindness of the great Legislator! Every word of God is pure in itself, and of great importance to us. He who cannot derive instruction from the chapter before him, and be led by a proper consideration of its contents to adore the wisdom and goodness of God, must have either a very stupid or a very vitiated mind.

2. In all these ordinances we may plainly see that God has purity of heart continually in view - that the soul may be holy, he cuts off the occasions of sin; and that men may be obliged to keep within due bounds, and possess their vessels in sanctification and honor, he hedges up their way with briars and thorns, and renders transgression painful, shameful, and expensive.

3. Preventing grace is not less necessary than that which saves and which preserves. These three chapters, avoided and neglected by most, contain lessons of instruction for all; and though many things contained in them belong exclusively to the Jewish people as to the letter, yet in their spirit and gracious design they form a part of those revealed things which are for us and for our children; and although they cannot be made the subject of public oral instruction, yet they are highly necessary to be known, and hence the advantage of reading the Scriptures in regular order in private.

May we read so as to understand, and practice what we know, that, being wise unto salvation, we may walk as children of the light and of the day, in whom there shall be no occasion of stumbling!

Thus 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.

Thus shall ye {l} separate the children of Israel from their uncleanness; that they die not in their uncleanness, when they defile my tabernacle that is among them.

(l) Seeing that God required purity and cleanliness of his own: we cannot be his, unless our filth and sins are purged with the blood of Jesus Christ, and so we learn to detest all sin.

15:31 When they defile my tabernacle - Both ceremonially, by coming into it in their uncleanness, and morally by the contempt of God's express command to cleanse themselves. The grand reason of all these laws was, to separate the children of Israel from their uncleanness. Hereby they were taught their privilege and honour, that they were purified unto God, a peculiar people; for that was a defilement to them, which was not so to others. They were also taught their duty, which was to keep themselves clean from all pollutions.

31-33. 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).

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.
