Numbers 19:13
19:13 Anyone 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, 1 because the water of purification was not sprinkled on him. He will be unclean; his uncleanness remains on him.
Numbers 19:20
19:20 But the man who is unclean and does not purify himself, that person must be cut off from among the community, because he has polluted the sanctuary of the Lord; the water of purification was not sprinkled on him, so he is unclean.
1 sn It is in passages like this that the view that being “cut off” meant the death penalty is the hardest to support. Would the Law prescribe death for someone who touches a corpse and fails to follow the ritual? Besides, the statement in this section that his uncleanness remains with him suggests that he still lives on.
