Numbers 15:30-31

30But 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].

31Because 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.’ ”
