Mbh 12.42.1a

"Vaisampayana said, 'Having heard those words, suitable to time and place, of his subjects, king Yudhishthira answered them in the following words, "Great must be the sons of Pandu, in sooth, whose merits, true or false, are thus recited by such foremost of Brahmanas assembled together. Without doubt, we are all objects of favour with you since you so freely describe us to be possessed of such attributes. King Dhritarashtra, however, is our father and god. If ye desire to do what is agreeable to me, always render your obedience to him and what is agreeable to him. Having slaughtered all my kinsmen, I live for him alone. My great duty is to always serve him in every respect with watchfulness. If ye, as also my friends, think that I should be an object of favour with you and them, let me then request you all to show the same behaviour towards Dhritarashtra as ye used to show before. He is the lord of the world, of yourselves, and of myself. The whole world, with the Pandavas, belongs to him. Ye should always bear these words of mine in your minds." The king then told them to go whithersoever they liked. Having dismissed the citizens and the people of the provinces, the delighter of the Kurus appointed his brother Bhimasena as Yuvaraja. And he cheerfully appointed Vidura of great intelligence for assisting him with his deliberations and for overlooking the sixfold requirements of the state.[125] And he appointed Sanjaya of mature years and possessed of every accomplishment, as general director and supervisor of the finances. And the king appointed Nakula for keeping the register of the forces, for giving them food and pay and for supervising other affairs of the army. And king Yudhishthira appointed Phalguna for resisting hostile forces and chastising the wicked. And he appointed Dhaumya, the foremost of priests, to attend daily to the Brahmanas and all rites in honour of the gods and other acts of a religious kind.
