He that spareth his rod hateth his son: but he that loveth him chasteneth him betimes.
Chasten thy son while there is hope, and let not thy soul spare for his crying.Proverbs 22:6, 15
Train up a child in the way he should go: and when he is old, he will not depart from it...Foolishness [is] bound in the heart of a child; [but] the rod of correction shall drive it far from him.
Proverbs 23:13, 14
Withhold not correction from the child: for [if] thou beatest him with the rod, he shall not die. Thou shalt beat him with the rod, and shalt deliver his soul from hell.
And all thy children [shall be] taught of the LORD; and great [shall be] the peace of thy children.Ephesians 6:4
And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.Colossians 3:21
