Numbers 19:11-16

11“‘Whoever touches the corpse of any person will be ceremonially unclean seven days.

12He must purify himself with water on the third day and on the seventh day, and so will be clean. But if he does not purify himself on the third day and the seventh day, then he will not be clean.

13Anyone who touches the corpse of any dead person and does not purify himself defiles the tabernacle of the Lord. And that person must be cut off from Israel, because the water of purification was not sprinkled on him. He will be unclean; his uncleanness remains on him.

14“‘This is the law: When a man dies in a tent, anyone who comes into the tent and all who are in the tent will be ceremonially unclean seven days.

15And every open container that has no covering fastened on it is unclean.

16And whoever touches the body of someone killed with a sword in the open fields, or the body of someone who died of natural causes, or a human bone, or a grave, will be unclean seven days.
