Mbh 5.137.1a

“Kunti said, ‘Say unto Arjuna, these words, “when thou wert brought forth in the lying-in room and when I was sitting in the hermitage surrounded by ladies, a celestial and delightful voice was heard in the sky, saying, ‘O Kunti, this thy son will rival the deity of a thousand eyes. This one will vanquish in battle all the assembled Kurus. Aided by Bhima, he will conquer the whole Earth and his fame will touch the very heavens. With Vasudeva as his ally, he will slay the Kurus in battle and recover his lost paternal share in the kingdom. Endued with great prosperity, he will, with his brothers, perform three great sacrifices.’” O thou of unfading glory, thou knowest how steady, in truth, is Vibhatsu, otherwise called Savyasachin, how irresistible he is. O thou of Dasarha’s race, let it be as that (celestial) voice said. If, O thou of Vrishni’s race, there is anything like righteousness, those words will be true, for then, Krishna, thou wilt thyself accomplish it all. I do not doubt what that voice said. I bow to righteousness which is superior to all. It is righteousness that supports all creatures. Thou shalt say these words unto Dhananjaya. Unto Vrikodara again, who is always ready for exertion, thou shalt say these words, “The time hath come for that in view of which Kshatriya lady bringeth forth a son! They that are foremost among men never become cheerless when they have hostilities to wage”--Thou knowest what the state of Bhima’s mind is. That grinder of foes is never pacified until he exterminates his foes. Thou shalt, O Madhava, next say unto the auspicious Krishna of great fame, that daughter-in-law of the high-souled Pandu, who is conversant with the details of every virtue, these words, “O thou that art highly blessed, O thou of noble parentage, O thou that art endued with great fame, that becoming behaviour which thou always showest towards my sons is, indeed, worthy of thee.”
