Numbers 19:13-19

13Anyone touching the dead body of any man, who does not purify himself, defiles Adonai’s Tabernacle, and that person will be cut off from Israel. Because the cleansing water was not sprinkled on him, he is unclean and his uncleanness will remain on him.

14“This is the Torah for whenever a person dies in a tent. Anyone entering the tent or anyone inside the tent will be unclean seven days.

15Any open container not having a lid fastened on it will also be unclean.

16Anyone out in the open field who touches a dead body, whether killed by a sword or was killed by a natural cause, or touches a human bone or a grave, shall be unclean seven days.

17“For the unclean one, they are to take some of the ash of the burnt purification offering, and pour some fresh water into a jar.

18Then a clean person will take some hyssop, dip it into the water, and, sprinkle it on the tent, all of the furnishings, and the people who were there, as well as the one touching the bone, the one killed, the corpse or the grave.

19The clean person will sprinkle the unclean one on the third and seventh days. He is to purify himself on the seventh day, and on the seventh day he is to wash his clothes and bathe himself in water, and at evening he will be clean.
