Mbh 5.149.1b

Unto that lion among kings, who ruled his kingdom virtuously were born three sons of great fame and resembling three gods. Of them, Devapi was the eldest, Vahlika the next and Santanu of great intelligence, who, O sire, was my grandfather, was the youngest. Devapi, endued with great energy, was virtuous, truthful in speech, and ever engaged in waiting upon his father. But that best of kings had a skin-disease. Popular with both the citizens and the subjects of the provinces, respected by the good, and dearly loved by the young and the old, Devapi was liberal firmly adhering to truth, engaged in the good of all creatures, and obedient to the instructions of his father as also of the Brahmanas. He was dearly loved by his brother Vahlika as also the high-souled Santanu. Great, indeed, was the brotherly love that prevailed between him and his high-souled brothers. In course of time, the old and best of kings, Pratipa, caused all preparations to be made according to the scriptures for the installation of Devapi (on the throne). Indeed, the lord Pratipa caused every auspicious preparation. The installation of Devapi, however, was forbidden by the Brahmanas and all aged persons amongst the citizens and the inhabitants of the provinces. Hearing that the installation of his son was forbidden, the voice of the old king became choked with tears and he began to grieve for his son. Thus, though Devapi was liberal, virtuous, devoted to truth, and loved by the subjects, yet in consequence of his skin-disease, he was excluded from his inheritance. The gods do not approve of a king that is defective of a limb. Thinking of this, those bulls among Brahmanas forbade king Pratipa to install his eldest son. Devapi then, who was defective of one limb, beholding the king (his father) prevented (from installing him on the throne) and filled with sorrow on his account, retired into the woods. As regards Vahlika, abandoning his (paternal) kingdom he dwelt with his maternal uncle.
