Scripture does nonetheless prescribe the rod of discipline as a necessary aspect of parenting. In fact, Scripture flatly contradicts modern opponents of corporal punishment: “He who spares his rod hates his son, but he who loves him disciplines him promptly” (Proverbs 13:24). “Foolishness is bound up in the heart of a child; the rod of correction will drive it far from him” (22:15). “You shall beat him with a rod, and deliver his soul from hell” (23:14; see also 10:13; 19:18).
