“If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and, though they discipline him, will not listen to them, then his father and his mother shall take hold of him and bring him out to the elders of his city at the gate of the place where he lives, and they shall say to the elders of his city, ‘This our son is stubborn and rebellious; he will not obey our voice; he is a glutton and a drunkard.’ Then all the men of the city shall stone him to death with stones. So you shall purge the evil from your midst, and all Israel shall hear, and fear.
“Whoever curses his father or his mother shall be put to death.
Do not withhold discipline from a child; if you strike him with a rod, he will not die. If you strike him with the rod, you will save his soul from Sheol.
For God commanded, ‘Honor your father and your mother,’ and, ‘Whoever reviles father or mother must surely die.’
Whoever spares the rod hates his son, but he who loves him is diligent to discipline him.
For anyone who curses his father or his mother shall surely be put to death; he has cursed his father or his mother; his blood is upon him.
“Whoever strikes his father or his mother shall be put to death.
A fool despises his father's instruction, but whoever heeds reproof is prudent.
