Numbers 15:30-34

But the person who does wrong defiantly, whether he is a native or a stranger, that one is blaspheming the Lord; and that person shall be cut off from among his people.

Since he has despised the word of the Lord and has broken His commandment, that person shall be completely cut off; his guilt will be on him.’ ” Sabbath-breaking Punished

Now while the sons of Israel were in the wilderness, they found a man gathering wood on the Sabbath day.

And those who found him gathering wood brought him to Moses and Aaron, and to all the congregation;

and they placed him in custody, because it had not been decided what should be done to him.
