Numbers 19:11-16

11“Whoever touches the dead body of any human being will be unclean for seven days.

12The unclean person must use this water on the third day and the seventh day to take away his sin. Then he will be clean. But if he doesn’t use this water on the third day and the seventh day, he will not be clean.

13Whoever touches the dead body of a human being and doesn’t use this water to take away his sin makes the Lord’s tent unclean. That person must be excluded from Israel, because the water that takes away uncleanness wasn’t sprinkled on him. He is unclean; his uncleanness stays with him.

14“These are your instructions for when a person dies in a tent: Everyone who goes into the tent and everyone who is in the tent will be unclean for seven days.

15Every container without a lid fastened on it is unclean.

16“Whoever is outdoors and touches someone who was killed or has died naturally or anyone who touches a human bone or a grave will be unclean for seven days.
