Numbers 19:11-16

11Any person who touches a dead body will not be clean for seven days.

12He must use the water to wash himself on the third day and on the seventh day. Then he will be clean. If he does not wash himself on the third day and on the seventh day, he will not be clean.

13A person might touch the body of a dead person. If he does not make himself clean, he has made the Lord's Tent of Meeting unclean. You must make that person separate from the Israelites. Because they did not splash the special water on him, he will not be clean. He will continue to be unclean.

14This is the rule when a person dies in a tent. Any person who is in the tent will not be clean for seven days.

15Any pot in the tent that does not have a lid will not be clean.

16Also, a person might have killed someone with a sword out in the country. Or someone may have died because he was old or ill. Anyone who touches a dead body in the country will become unclean for seven days. Also if they touch a human bone, or a grave, that person will be unclean for seven days.
