Mahabharata Karna parva Chapter 41:7

Mahabharata Karna parva Chapter 41:7 Beholding also thy brother slain by Savyasaci, in the very sight of the Kuru heroes, it was thou that didst fly away first. By the skirts also of the dvaitya lake, O Karna, when thou wert assailed by the Gandharvas, it was thou that, deserting all the Kurus, didst first run away. Having vanquished in battle the Gandharvas headed by Citrasena, with great slaughter, it was Partha, O Karna, that liberated Duryodhana with his wife. Rama himself, O Karna, before the kings in the (Kuru) assembly spake of the great prowess of both Partha and Keshava. Thou didst frequently hear the words of Drona and Bhishma, speaking in the presence of all the kings, that the two Krishnas are unslayable. I have told thee a little only regarding those matters in which Dhananjaya is superior to thee like the Brahmana who is superior to all created beings. Soon wilt thou see, stationed on that foremost of cars, the son of Vasudeva and the son of Kunti and Pandu. As the crow (in the story), acting with intelligence, had sought the protection of the swan, so do thou seek the protection of him of Vrishni's race, and of Pandu's son Dhananjaya. When thou shalt in battle behold Vasudeva and Dhananjaya, those two endued with great prowess, stationed together on the same car, thou shalt not then, O Karna, utter such speeches. When Partha will, with hundreds of arrows, quell thy pride, then wilt thou behold the difference between thyself and Dhananjaya. Those two best of persons are celebrated among the gods, the Asuras and human beings. Thou that art a firefly, do not, from folly, think disrespectfully of those two resplendent luminaries. Like the Sun and moon, Keshava and Arjuna are celebrated for their resplendence. Thou, however, art like a fire-fly among men. O learned one, O son of a Suta, do not think disrespectfully of Acyuta and Arjuna. Those two high-souled persons are lions among men. Forbear indulging in such boasts.
