Bible on corporal punishment for children

Proverbs 13 vs. 24

He that spareth his rod hateth his son: but he that loveth him chasteneth him betimes.

Proverbs 23 vs. 13

Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.

Proverbs 29 vs. 15

The rod and reproof give wisdom: but a child left to himself bringeth his mother to shame.

Proverbs 29 vs. 17

Correct thy son, and he shall give thee rest; yea, he shall give delight unto thy soul.
