Numbers 19:13-19

13All 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.

15Any open container in the tent that was not covered with a lid is also defiled.

16And 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.

18Then 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.

19On the third and seventh days the person who is ceremonially clean must sprinkle the water on those who are defiled. 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.
