Numbers 19:11-16

11“Whoever touches a human corpse will be unclean for seven days. 12They must purify themselves with the water on the third day and on the seventh day; then they will be clean. But if they do not purify themselves on the third and seventh days, they will not be clean. 13If they fail to purify themselves after touching a human corpse, they defile the Lord’s tabernacle. They must be cut off from Israel. Because the water of cleansing has not been sprinkled on them, they are unclean; their uncleanness remains on them. 14“This is the law that applies when a person dies in a tent: Anyone who enters the tent and anyone who is in it will be unclean for seven days, 15and every open container without a lid fastened on it will be unclean. 16“Anyone out in the open who touches someone who has been killed with a sword or someone who has died a natural death, or anyone who touches a human bone or a grave, will be unclean for seven days.
