'Cutoff' in the Bible

But the man who is [ceremonially] clean and is not on a journey, and yet does not observe the Passover, that person shall be cut off from among his people [excluding him from the atonement made for them] because he did not bring the Lord’s offering at its appointed time; that man will bear [the penalty of] his sin.

But the person who does [anything wrong] willfully and defiantly, whether he is native-born or a stranger, that one is blaspheming the Lord, and that person shall be cut off from among his people [excluding him from the atonement made for them].

Because he has despised and rejected the word of the Lord, and has broken His commandment, that person shall be utterly cut off; [the responsibility for] his wickedness and guilt will be upon him.’”

Whoever touches a corpse, the body of anyone who has died, and does not purify himself, defiles the tabernacle of the Lord; and that person shall be cut off from Israel [that is, excluded from the atonement made for them]. Because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is still on him.

‘But the man who is unclean and does not purify himself, that person shall be cut off from among the assembly, because he has defiled the sanctuary of the Lord. The water for purification has not been sprinkled on him; he is unclean.
