Leviticus 24:12-16

12So they placed him in custody until they were able to make a clear legal decision for themselves based on words from the mouth of the Lord.

13Then the Lord spoke to Moses:

14“Bring the one who cursed outside the camp, and all who heard him are to lay their hands on his head, and the whole congregation is to stone him to death.

15Moreover, you are to tell the Israelites, ‘If any man curses his God he will bear responsibility for his sin,

16and one who misuses the name of the Lord must surely be put to death. The whole congregation must surely stone him, whether he is a foreigner or a native citizen; when he misuses the Name he must be put to death.
