Mbh 16.6.2a

"'Vasudeva said, "Without beholding those heroes, O Arjuna, who had subjugated all the kings of the Earth and the Daityas a hundred times, I am still alive! Methinks, I have no death! Through the fault of those two heroes who were thy dear disciples and who were much regarded by thee, also, O Partha, the Vrishnis have been destroyed. Those two who were regarded as Atirathas amongst the foremost of the Vrishnis, and referring to whom in course of conversation thou wert wont to indulge in pride, and who, O chief of Kuru's race, were ever dear to Krishna himself, alas, those two, O Dhananjaya, have been the chief causes of the destruction of the Vrishnis! I do not censure the son of Sini or the son of Hridika, O Arjuna. I do not censure Akrura or the son of Rukmini. No doubt, the curse (of the Rishis) is the sole cause. How is it that that lord of the universe, the slayer of Madhu, who had put forth his prowess for achieving the destruction of Kesin and Kansa, and Chaidya swelling with pride, and Ekalavya, the son of the ruler of the Nishadas, and the Kalingas and the Magadhas, and the Gandharas and the king of Kasi, and many rulers assembled together in the midst of the desert, many heroes belonging to the East and the South, and many kings of the mountainous regions, alas, how could he remain indifferent to such a calamity as the curse denounced by the Rishis? Thyself, Narada, and the Munis, knew him to be the eternal and sinless Govinda, the Deity of unfading glory. Alas, being puissant Vishnu himself, he witnessed, without interfering, the destruction of his kinsmen! My son must have himself allowed all this to happen. He was the Lord of the universe. He did not, however, wish to falsify the words of Gandhari and the Rishis, O scorcher of foes. In thy very sight, O hero, thy grandson, who had been slain by Ashvatthama, was revived through his energy. That friend, however, of yours did not wish to protect his kinsmen.
