Mbh 5.132.2c

A virtuous person, upon acquiring a kingdom, should in this world make all persons his own, attaching some by gift, some by force, and some by sweet words. A Brahmana should adopt mendicancy; a Kshatriya should protect (subjects); a Vaisya should earn wealth; and a Sudra should serve the other three. Mendicancy, therefore, is forbidden to thee. Nor is agriculture suited to thee. Thou art a Kshatriya and therefore, the protector of all in distress. Thou art to live by the prowess of thy arms. O thou of mighty arms, recover thy paternal share of the kingdom which thou hast lost, by conciliation, or by working disunion among thy foes, or by gift of money or violence, or well-directed policy. What can be a matter of greater grief than that I, deprived of friends, should live upon food supplied by others, after having brought thee forth, thou enhancer of the joys of friends? Fight, according to the practices of kings. Do not sink thy ancestors (in infamy). With thy merit worn out, do not, with thy younger brothers, obtain a sinful end.”’”
