Mbh 14.62.1a

"Vaisampayana said, 'Having heard these words of his son Vasudeva, that descendant of Sura, of righteous soul, casting off his grief, made excellent obsequial offerings (unto Abhimanyu). Vasudeva also performed those rites for the ascension (to Heaven) of his high-souled nephew, that hero who was ever the darling of his sire (Vasudeva). He duly fed six millions of Brahmanas, endued with great energy, with edibles possessed of every recommendation. Presenting many clothes unto them, Krishna gratified the thirst for wealth of those Brahmanas. Wonderful were the heaps of gold, the number of kine and of beds and clothes, that were then given away. The Brahmanas loudly declared--"Let (Krishna's wealth) increase." Then Vasudeva of Dasarha's race, and Valadeva, and Satyaki, and Satyaka, each performed the obsequial rites of Abhimanyu. Exceedingly afflicted with grief, they failed to attain comfort. The same was the case with the sons of Pandu in the city called after the elephant. Deprived of Abhimanyu, they failed to obtain peace of mind. The daughter of Virata, O monarch, for many days, totally abstained from all food, exceedingly afflicted by grief on account of the death of her husband. At this all her relatives became plunged into excess of grief. They all feared that the embryo in her womb might be destroyed. Then Vyasa, ascertaining the state of things by his spiritual vision, came there. The highly intelligent Rishi, endued with great energy, arrived (at the palace), addressed Pritha of large eyes, as also Uttara herself, saying,--"Let this grief be abandoned. O famous lady, a son endued with mighty energy will be born to thee, through the puissance of Vasudeva and at my word. That son will rule the Earth after the Pandavas (have departed from it)." Beholding Dhananjaya, he said unto him, in the hearing of king Yudhishthira the just, and gladdening him with his words, "O Bharata, thy grandson, O highly blessed one, will become a high-souled prince.
