Leviticus 15

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.

Chapter 15 In this chapter we have laws concerning other ceremonial uncleannesses contracted either by bodily disease like that of the leper, or some natural incidents, and this either, I. In men (v. 1–18). Or, II. In women (v. 19–33). We need not be at all curious in explaining these antiquated laws, it is enough if we observe the general intention; but we have need to be very cautious lest sin take occasion by the commandment to become more exceedingly sinful; and exceedingly sinful it is when lust is kindled by sparks of fire from God’s altar. The case is bad with the soul when it is putrefied by that which should purify it.Verses 1-18 We have here the law concerning the ceremonial uncleanness that was contracted by running issues in men. It is called in the margin (v. 2) the running of the reins: a very grievous and loathsome disease, which was, usually the effect and consequent of wantonness and uncleanness, and a dissolute course of life, filling men’s bones with the sins of their youth, and leaving them to mourn at the last, when all the pleasures of their wickedness have vanished, and nothing remains but the pain and anguish of a rotten carcase and a wounded conscience. And what fruit has the sinner then of those things whereof he has so much reason to be ashamed? Rom. 6:21. As modesty is an ornament of grace to the head and chains about the neck, so chastity is health to the navel and marrow to the bones; but uncleanness is a wound and dishonour, the consumption of the flesh and the body, and a sin which is often its own punishment more than any other. It was also sometimes inflicted by the righteous hand of God for other sins, as appears by David’s imprecation of a curse upon the family of Joab, for the murder of Abner. 2 Sa. 3:29, Let there not fail from the house of Joab one that hath an issue, or is a leper. A vile disease for vile deserts. Now whoever had this disease upon him, 1. He was himself unclean, v. 2. He must not dare to come near the sanctuary, it was at his peril if he did, nor might he eat of the holy things. This signified the filthiness of sin, and of all the productions of our corrupt nature, which render us odious to God’s holiness, and utterly unfit for communion with him. Out of a pure heart well kept are the issues of life (Prov. 4:23), but out of an unclean heart comes that which is defiling, Mt. 12:34, 35. 2. He made every person and thing unclean that he touched, or that touched him, v. 4–12. His bed, and his chair, and his saddle, and every thing that belonged to him, could not be touched without a ceremonial uncleanness contracted, which a man must remain conscious to himself of till sunset, and from which he could not be cleansed without washing his clothes, and bathing his flesh in water. This signified the contagion of sin, the danger we are in of being polluted by conversing with those that are polluted, and the need we have with the utmost circumspection to save ourselves from this untoward generation. 3. When he was cured of the disease, yet he could not be cleansed from the pollution without a sacrifice, for which he was to prepare himself by seven days’ expectation after he was perfectly clear from his distemper, and by bathing in spring water, v. 13–15. This signified the great gospel duties of faith and repentance, and the great gospel privileges of the application of Christ’s blood to our souls for our justification and his grace for our sanctification. God has promised to sprinkle clean water upon us, and to cleanse us from all our filthiness, and has appointed us by repentance to wash and make ourselves clean: he has also provided a sacrifice of atonement, and requires us by faith to interest ourselves in that sacrifice; for it is the blood of Christ his Son that cleanses us from all sin, and by which atonement is made for us, that we may have admission into God’s presence and may partake of his favour.

2. When any man hath a running issue—This chapter describes other forms of uncleanness, the nature of which is sufficiently intelligible in the text without any explanatory comment. Being the effects of licentiousness, they properly come within the notice of the legislator, and the very stringent rules here prescribed, both for the separation of the person diseased and for avoiding contamination from anything connected with him, were well calculated not only to prevent contagion, but to discourage the excesses of licentious indulgence.

12. the vessel of earth, that he toucheth which hath the issue, shall be broken—It is thought that the pottery of the Israelites, like the earthenware jars in which the Egyptians kept their water, was unglazed and consequently porous, and that it was its porousness which, rendering it extremely liable to imbibe small particles of impure matter, was the reason why the vessel touched by an unclean person was ordered to be broken.

13, 14. then he shall number to himself seven days for his cleansing—Like a leprous person he underwent a week's probation, to make sure he was completely healed. Then with the sacrifices prescribed, the priest made an atonement for him, that is, offered the oblations necessary for the removal of his ceremonial defilement, as well as the typical pardon of his sins.
