9 And a clean man shall gather the ashes of the heifer, and deposit them outside the camp in a clean place, and it shall be kept for the assembly of the children of Israel for a water of separation: it is a purification for sin. 10 And he that hath gathered the ashes of the heifer shall wash his clothes, and be unclean until the even. And it shall be unto the children of Israel, and unto the stranger that sojourneth among them, an everlasting statute.
11 He that toucheth a dead person, any dead body of a man, shall be unclean seven days. 12 He shall purify himself with it on the third day, and on the seventh day he shall be clean; but if he purify not himself the third day, then the seventh day he shall not be clean. 13 Whoever toucheth a dead person, the dead body of a man that is dead, and purifieth not himself, defileth the tabernacle of Jehovah; and that soul shall be cut off from Israel; for the water of separation was not sprinkled upon him: he shall be unclean; his uncleanness is yet upon him. 14 This is the law, when a man dieth in a tent: every one that cometh into the tent, and all that is in the tent, shall be unclean seven days. 15 And every open vessel, which hath no covering bound upon it, shall be unclean. 16 And every one that toucheth one that is slain with a sword in the open fields, or a dead person, or the bone of a man, or a grave, shall be unclean seven days. 17 And they shall take for the unclean of the ashes of the purification-offering that hath been burned, and shall put running water thereon in a vessel; 18 and a clean man shall take hyssop, and dip it in the water, and sprinkle it on the tent, and upon all the utensils, and upon the persons that were there, and upon him that hath touched the bone, or the one slain, or the dead person, or the grave;

Commentary on Numbers 19:1-10
(Read Numbers 19:1-10)
The heifer was to be wholly burned. This typified the painful sufferings of our Lord Jesus, both in soul and body, as a sacrifice made by fire, to satisfy God's justice for man's sin. These ashes are said to be laid up as a purification for sin, because, though they were only to purify from ceremonial uncleanness, yet they were a type of that purification for sin which our Lord Jesus made by his death. The blood of Christ is laid up for us in the word and sacraments, as a fountain of merit, to which by faith we may have constant recourse, for cleansing our consciences.
Commentary on Numbers 19:11-22
(Read Numbers 19:11-22)
Why did the law make a corpse a defiling thing? Because death is the wages of sin, which entered into the world by it, and reigns by the power of it. The law could not conquer death, nor abolish it, as the gospel does, by bringing life and immortality to light, and so introducing a better hope. As the ashes of the heifer signified the merit of Christ, so the running water signified the power and grace of the blessed Spirit, who is compared to rivers of living water; and it is by his work that the righteousness of Christ is applied to us for our cleansing. Those who promise themselves benefit by the righteousness of Christ, while they submit not to the grace and influence of the Holy Spirit, do but deceive themselves; we cannot be purified by the ashes, otherwise than in the running water. What use could there be in these appointments, if they do not refer to the doctrines concerning the sacrifice of Christ? But comparing them with the New Testament, the knowledge to be got from them is evident. The true state of fallen man is shown in these institutions. Here we learn the defiling nature of sin, and are warned to avoid evil communications.
