paurajānapadānāṃ ca saṃmataḥ sādhusatkṛtaḥ |

Angry Yayati also cursed those brothers of Yadu who were obedient to that eldest brother of theirs, who was so proud of his strength. And having cursed his these sons, that best of kings placed on his throne his youngest son Puru who was docile and obedient to him. Thus even the eldest son may be passed over and deprived of the kingdom, and younger sons may, in consequence of their respectful behaviour to the aged, obtain the kingdom. So also, conversant with every virtue there was my father's grandfather, king Pratipa, who was celebrated over the three worlds. 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.
