While the children are young, the primary (though not the only) means of chastisement will be the literal rod. (Compare Prov. 13:24; 22:15; 23:13-14; 29:15). The rod is a merciful form of discipline, because it is quickly administered. The lesson is learned swiftly, hugs and kisses can come immediately, reconciliation and restoration to normal relations is experienced with hardly any delay.
