1 And the LORD spake unto Moses and to Aaron, saying,   2 Speak unto the children of Israel, and say unto them, When any man hath a running issue out of his flesh, because of his issue he is unclean.   3 And this shall be his uncleanness in his issue: whether his flesh run with his issue, or his flesh be stopped from his issue, it is his uncleanness.   4 Every bed, whereon he lieth that hath the issue, is unclean: and every thing, whereon he sitteth, shall be unclean.   5 And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.   6 And he that sitteth on any thing whereon he sat that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.   7 And he that toucheth the flesh of him that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.   8 And if he that hath the issue spit upon him that is clean; then he shall wash his clothes, and bathe himself in water, and be unclean until the even.   9 And what saddle soever he rideth upon that hath the issue shall be unclean.   10 And whosoever toucheth any thing that was under him shall be unclean until the even: and he that beareth any of those things shall wash his clothes, and bathe himself in water, and be unclean until the even.   11 And whomsoever he toucheth that hath the issue, and hath not rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.   12 And the vessel of earth, that he toucheth which hath the issue, shall be broken: and every vessel of wood shall be rinsed in water.   13 And when he that hath an issue is cleansed of his issue; then he shall number to himself seven days for his cleansing, and wash his clothes, and bathe his flesh in running water, and shall be clean.   14 And on the eighth day he shall take to him two turtledoves, or two young pigeons, and come before the LORD unto the door of the tabernacle of the congregation, and give them unto the priest:   15 And the priest shall offer them, the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for him before the LORD for his issue.   16 And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even.   17 And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even.   18 The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.

      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. vi. 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 Sam. iii. 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. iv. 23), but out of an unclean heart comes that which is defiling, Matt. xii. 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.
