11 'He who touches the dead body of anyone shall be unclean seven days. 12 He shall purify himself with the water on the third day and on the seventh day; then he will be clean. But if he does not purify himself on the third day and on the seventh day, he will not be clean. 13 Whoever touches the body of anyone who has died, and does not purify himself, defiles the tabernacle of the Lord. That person shall be cut off from Israel. He shall be unclean, because the water of purification was not sprinkled on him; his uncleanness is still on him. 14 'This is the law when a man dies in a tent: All who come into the tent and all who are in the tent shall be unclean seven days; 15 and every open vessel, which has no cover fastened on it, is unclean. 16 Whoever in the open field touches one who is slain by a sword or who has died, or a bone of a man, or a grave, shall be unclean seven days. 17 And for an unclean person they shall take some of the ashes of the heifer burnt for purification from sin, and running water shall be put on them in a vessel. 18 A clean person shall take hyssop and dip it in the water, sprinkle it on the tent, on all the vessels, on the persons who were there, or on the one who touched a bone, the slain, the dead, or a grave. 19 The clean person shall sprinkle the unclean on the third day and on the seventh day; and on the seventh day he shall purify himself, wash his clothes, and bathe in water; and at evening he shall be clean. 20 'But the man who is unclean and does not purify himself, that person shall be cut off from among the assembly, because he has defiled the sanctuary of the Lord. The water of purification has not been sprinkled on him; he is unclean. 21 It shall be a perpetual statute for them. He who sprinkles the water of purification shall wash his clothes; and he who touches the water of purification shall be unclean until evening. 22 Whatever the unclean person touches shall be unclean; and the person who touches it shall be unclean until evening.' "

(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.
