9 Then someone who is ceremonially clean will gather up the ashes of the heifer and deposit them in a purified place outside the camp. They will be kept there for the community of Israel to use in the water for the purification ceremony. This ceremony is performed for the removal of sin. 10 The man who gathers up the ashes of the heifer must also wash his clothes, and he will remain ceremonially unclean until evening. This is a permanent law for the people of Israel and any foreigners who live among them.
11 "All those who touch a dead human body will be ceremonially unclean for seven days. 12 They must purify themselves on the third and seventh days with the water of purification; then they will be purified. But if they do not do this on the third and seventh days, they will continue to be unclean even after the seventh day. 13 All those who touch a dead body and do not purify themselves in the proper way defile the Lord 's Tabernacle, and they will be cut off from the community of Israel. Since the water of purification was not sprinkled on them, their defilement continues. 14 "This is the ritual law that applies when someone dies inside a tent: All those who enter that tent and those who were inside when the death occurred will be ceremonially unclean for seven days. 15 Any open container in the tent that was not covered with a lid is also defiled. 16 And if someone in an open field touches the corpse of someone who was killed with a sword or who died a natural death, or if someone touches a human bone or a grave, that person will be defiled for seven days. 17 "To remove the defilement, put some of the ashes from the burnt purification offering in a jar, and pour fresh water over them. 18 Then someone who is ceremonially clean must take a hyssop branch and dip it into the water. That person must sprinkle the water on the tent, on all the furnishings in the tent, and on the people who were in the tent; also on the person who touched a human bone, or touched someone who was killed or who died naturally, or touched a 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.
