10. Do not laugh with him lest you share sorrow with him,and in the end you will gnash your teeth.
11. Do not give him his own way in his youth,and do not ignore his follies.
12. Bow down his head in his youth,beat his sides while he is still young,Lest he become stubborn and disobey you,and leave you disconsolate.
13. Discipline your son and make heavy his yoke,lest you be offended by his shamelessness.
