Proverbs 13:24

v. 24. He that spareth his rod hateth his son, for it is not love, but the lack of love, which causes parents to forget and set aside their parental power and duty in correcting their children, if necessary, with the rod; but he that loveth him chasteneth him betimes, applying correction in the measure required by the occasion, Proverbs 3:12; Proverbs 23:13; Proverbs 29:15.
