The Lord speaks to Moses and Aaron and commands them to bring a red heifer, without defect or blemish, one that has never been under a yoke. It is given to the priest Eleazar, who leads it outside the camp, where it is slaughtered in his presence. Eleazar takes some of the blood and sprinkles it seven times toward the front of the tabernacle. Then the whole heifer is burned, and cedar wood, hyssop and scarlet yarn are thrown into the fire.
Those who take part in the rite, the priest and the man who burns the heifer, are unclean until evening and must wash their clothes and bathe in water. A clean man gathers the ashes and places them in a clean place outside the camp, where the congregation keeps them to prepare the water of purification. The text calls this a purification from sin and declares it a permanent statute, including for the foreigner who lives among them.
The second part applies the rite. Anyone who touches a dead body is unclean for seven days and must purify himself with the water on the third day and the seventh; if he does not, he defiles the Lord's tabernacle and is cut off from Israel. The same rules apply inside a tent where someone dies and to anyone who touches a bone or a grave. To apply the water, a clean man dips hyssop in the ashes-and-water mixture and sprinkles the tent, the vessels and the people. On the seventh day the person washes his clothes, bathes and is clean by evening.
