He who spares his rod hates his son, but he who loves him disciplines him diligently. (Proverbs 13:24).
Foolishness is bound up in the heart of a child; the rod of discipline will remove it far from him. (Proverbs 22:15).
Discipline your son while there is hope, and do not desire his death. (Proverbs 19:18).
The rod and reproof give wisdom, but a child who gets his own way brings shame to his mother…Correct your son, and he will give you comfort; he will also delight your soul. (Proverbs 29:15, 17).
Do not withhold discipline from a child; if you punish him with the rod, he will not die. Punish him with the rod and save his soul from death. (Proverbs 23:13-14, NIV).
What son is there whom his father does not discipline? But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons…All discipline for the moment seems not to be joyful, but sorrowful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness. (Hebrews 12:7-8, 11).
