Numbers 19:13-19

13Anyone who touches a human corpse and fails to purify himself defiles the tabernacle of the LORD. That person must be cut off from Israel. He remains unclean, because the water of purification has not been sprinkled on him, and his uncleanness is still on him.

14This is the law when a person dies in a tent: Everyone who enters the tent and everyone already in the tent will be unclean for seven days, 15and any open container without a lid fastened on it is unclean.

16Anyone in the open field who touches someone who has been killed by the sword or has died of natural causes, or anyone who touches a human bone or a grave, will be unclean for seven days.

17For the purification of the unclean person, take some of the ashes of the burnt sin offering, put them in a jar, and pour fresh water1 over them. 18Then a man who is ceremonially clean is to take some hyssop, dip it in the water, and sprinkle the tent, all the furnishings, and the people who were there. He is also to sprinkle the one who touched a bone, a grave, or a person who has died or been slain.

19The man who is ceremonially clean is to sprinkle the unclean person on the third day and on the seventh day. After he purifies the unclean person on the seventh day, the one being cleansed must wash his clothes and bathe in water, and that evening he will be clean.
