This is concerning the ceremonial uncleanness which women lay under from their issues, both those that were regular and healthful, and according to the course of nature (Lev 15:19-24), and those that were unseasonable, excessive, and the disease of the body; such was the bloody issue of that poor woman who was suddenly cured by touching the hem of Christ's garment, after she had lain twelve years under her distemper, and had spent her estate upon physicians and physic in vain. This made the woman that was afflicted with it unclean (Lev 15:25) and every thing she touched unclean, Lev 15:26, Lev 15:27. And if she was cured, and found by seven days' trial that she was perfectly free from her issue of blood, she was to be cleansed by the offering of two turtle-doves or two young pigeons, to make an atonement for her, Lev 15:28, Lev 15:29. All wicked courses, particularly idolatries, are compared to the uncleanness of a removed woman (Eze 36:17), and, in allusion to this, it is said of Jerusalem (Lam 1:9), Her filthiness is in her skirts, so that (as it follows, Lev 15:17) she was shunned as a menstruous woman.

I.The reasons given for all these laws (which we are ready to think might very well have been spared) we have, Lev 15:31. 1. Thus shall you separate the children of Israel (for to them only and their servants and proselytes these laws pertained) from their uncleanness; that is, (1.) By these laws they were taught their privilege and honour, that they were purified unto God a peculiar people, and were intended by the holy God for a kingdom of priests, a holy nation; for that was a defilement to them which was not so to others. (2.) They were also taught their duty, which was to preserve the honour of their purity, and to keep themselves from all sinful pollutions. It was easy for them to argue that if those pollutions which were natural, unavoidable, involuntary, their affliction and not their sin, rendered them for the time so odious that they were not fit for communion either with God or man, much more abominable and filthy were they if they sinned against the light and law of nature, by drunkenness, adultery, fraud, and the like sins, which defile the very mind and conscience. And, if these ceremonial pollutions could not be done away but by sacrifice and offering, something greater and much more valuable must be expected and depended upon for the purifying of the soul from the uncleanness of sin. 2. Thus their dying in their uncleanness by the hand of God's justice, if while they were under any of these defilements they should come near the sanctuary, would be prevented. Note, It is a dangerous thing to die in our uncleanness; and it is our own fault if we do, since we have not only fair warning given us, by God's law, against those things that will defile us, but also such gracious provision made by his gospel for our cleansing if at any time we be defiled. 3. In all these laws there seems to be a special regard had to the honour of the tabernacle, to which none must approach in their uncleanness, that they defile not my tabernacle. Infinite Wisdom took this course to preserve in the minds of that careless people a continual dread of, and veneration for, the manifestations of God's glory and presence among them in his sanctuary. Now that the tabernacle of God was with men familiarity would be apt to breed contempt, and therefore the law made so many things of frequent incidence to be ceremonial pollutions, and to involve an incapacity of drawing near to the sanctuary (making death the penalty), that so they might not approach without great caution, and reverence, and serious preparation, and fear of being found unfit. Thus they were taught never to draw near to God but with an awful humble sense of their distance and danger, and an exact observance of every thing that was required in order to their safety and acceptance.

II.And what duty must we learn from all this? 1. Let us bless God that we are not under the yoke of these carnal ordinances, that, as nothing can destroy us, so nothing can defile us, but sin. Those may now partake of the Lord's supper who durst not then eat of the peace-offerings. And the defilement we contract by our sins of daily infirmity we may be cleansed from in secret by the renewed acts of repentance and faith, without bathing in water or bringing an offering to the door of the tabernacle. 2. Let us carefully abstain from all sin, as defiling to the conscience, and particularly from all fleshly lusts, possessing our vessel in sanctification and honour, and not in the lusts of uncleanness, which not only pollute the soul, but war against it, and threaten its ruin. 3. Let us all see how indispensably necessary real holiness is to our future happiness, and get our hearts purified by faith, that we may see God. Perhaps it is in allusion to these laws which forbade the unclean to approach the sanctuary that when it is asked, Who shall stand in God's holy place? it is answered, He that hath clean hands and a pure heart (Psa 24:3, Psa 24:4); for without holiness no man shall see the Lord.

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!

And of her that is sick of her flowers,.... Her monthly courses, for these are a sickness, Lev 20:18; and make a woman languid and faint, as the word is rendered, Lam 1:13; or to be in pain (n), as some render it here; and pains are reckoned among the signs of them by the Misnic doctors (o):

and of him that hath an issue, of the man, and of the woman; of both, whether the one or the other:

and of him that lieth with her that is unclean; though her own husband.

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 (Th1 4:4).
