"To remove the defilement, put some of the ashes from the burnt purification offering in a jar and pour fresh water over them.
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 anyone who was in the tent, or anyone who has touched a human bone, or has touched a person who was killed or who died naturally, or has touched a grave.
On the third and seventh days the ceremonially clean person must sprinkle the water on those who are unclean. Then on the seventh day the people being cleansed must wash their clothes and bathe themselves, and that evening they will be cleansed of their defilement."
"But those who become defiled and do not purify themselves will be cut off from the community, for they have defiled the sanctuary of the LORD. Since the water of purification has not been sprinkled on them, they remain defiled.
This is a permanent law. Those who sprinkle the water of purification must afterward wash their clothes, and anyone who touches the water of purification will remain defiled until evening.
Anything and anyone that a defiled person touches will be ceremonially defiled until evening."
