Mbh 3.206.3a

“Markandeya continued, ‘So be it,’ said the Brahmana unto him, gladly. And thereupon, the fowler proceeded towards his home with the Brahmana walking before him. And entering his abode that looked delightful, the fowler reverenced his guest by offering him a seat. And he also gave him water to wash his feet and face. And accepting these, that best of Brahmanas sat at his ease And he then addressed the fowler, saying, ‘It seems to me that this profession doth not befit thee. O fowler, I deeply regret that thou shouldst follow such a cruel trade.’ At these words of the Brahmana the fowler said, ‘This profession is that of my family, myself having inherited it from my sires and grandsires. O regenerate one, grieve not for me owing to my adhering to the duties that belong to me by birth. Discharging the duties ordained for me beforehand by the Creator, I carefully serve my superiors and the old. O thou best of Brahmanas! I always speak the truth, never envy others; and give to the best of my power. I live upon what remaineth after serving the gods, guests, and those that depend on me. I never speak ill of anything, small or great. O thou best of Brahmanas, the actions of a former life always follow the doer. In this world there are three principal professions, viz., agriculture, rearing of cattle, and trade. As regards the other world, the three Vedas, knowledge, and the science of morals are efficacious. Service (of the other three orders) hath been ordained to be the duty of the Sudra. Agriculture hath been ordained for the Vaisyas, and fighting for the Kshatriyas, while the practice of the Brahmacharya vow, asceticism, recitation of mantras, and truthfulness have been ordained for the Brahmanas. Over subjects adhering to their proper duties, the king should rule virtuously; while he should set those thereto that have fallen away from the duties of their order. Kings should ever be feared, because they are the lords of their subjects.
