Leviticus 24:21

24:21 One who beats an animal to death must make restitution for it, but one who beats a person to death must be put to death.

Leviticus 24:16

24:16 and 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.
