Numbers 19:13

Context19:13 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 19:19
Context19:19 And the clean person must sprinkle the unclean on the third day and on the seventh day; and on the seventh day he must purify him, 2 and then he must wash his clothes, and bathe in water, and he will be clean in the evening.
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.
2 tn The construction uses a simple Piel of חָטָא (khata’, “to purify”) with a pronominal suffix – “he shall purify him.” Some commentators take this to mean that after he sprinkles the unclean then he must purify himself. But that would not be the most natural way to read this form.
