Numbers 19:11-16

11“Whoever touches any dead body will be unclean for seven days.

12He is to purify himself on the third day and on the seventh day. Then he will be clean. But if he does not purify himself on the third and seventh days, he will not be clean.

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.
