Mbh 5.149.1c

Abandoning his father and brother, he obtained the highly wealthy kingdom of his maternal grandfather. With Vahlika’s permission, O prince, Santanu of world-wide fame, on the death of his father (Pratipa), became king and ruled the kingdom. In this way also, O Bharata, though I am the eldest, yet being defective of a limb, I was excluded from the kingdom by intelligent Pandu, no doubt, after much reflection. And Pandu himself, though younger to me in age, obtained the kingdom and became king. At his death, O chastiser of foes, that kingdom must pass to his sons. When I could not obtain the kingdom, how canst thou covet it? Thou art not the son of a king, and, therefore, hast no right to this kingdom. Thou, however, desirest to appropriate the property of others. High-souled Yudhishthira is the son of a king. This kingdom is lawfully his. Of magnanimous soul, even he is the ruler and lord of this race of Kuru. He is devoted to truth, of clear perception, obedient to the counsels of friends, honest, loved by the subjects, kind to all well-wishers, master of his passions, and the chastiser of all that are not good. Forgiveness, renunciation, self-control, knowledge of the scriptures, mercy to all creatures, competence to rule according to the dictates of virtue, of all these attributes of royalty exist in Yudhishthira. Thou art not the son of a king, and art always sinfully inclined towards thy relatives. O wretch, how canst thou succeed in appropriating this kingdom that lawfully belongeth to others? Dispelling this delusion, give half the kingdom with (a share of the) animals and other possessions. Then, O king, mayest thou hope to live for some time with thy younger brothers.”’”
