Numbers 5:27

5:27 When he has made her drink the water, then, if she has defiled herself and behaved unfaithfully toward her husband, the water that brings a curse will enter her to produce bitterness – her abdomen will swell, her thigh will fall away, and the woman will become a curse among her people.

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 35:34

35:34 Therefore do not defile the land that you will inhabit, in which I live, for I the Lord live among the Israelites.”

[19:13]  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.
