" He who withholds his rod hates his son, but he who loves him disciplines him diligently (Proverbs 13:24). Discipline your son while there is hope, and do not desire his death (Proverbs 19:18). Foolishness is bound up in the heart of a child; the rod of discipline will remove it far from him (Proverbs 22:15). Do not hold back discipline from the child, although you strike him with the rod, he will not die. You shall strike him with the rod and rescue his soul from Sheol (Proverbs 23:13-14). 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). "
