Mbh 8.39.3b

Thou desirest to cross without a raft the terrible ocean, the receptacle of all the waters, with its mountain waves and teeming with aquatic animals, when at its height at the rise of the Moon. O Karna, thou challengest Dhananjaya, the son of Pritha, to battle even like a calf challenging a smiting bull of keen horns and neck thick as a drum. Like a frog croaking at a terrible and mighty cloud yielding copious showers of rain, thou croakest at Arjuna who is even like Parjanya among men. As a dog from within the precincts of the house of his master barks at a forest-roaming tiger, even so, O Karna, thou barkest at Dhananjaya, that tiger among men. A jackal, O Karna, residing in the forest in the midst of hares regardeth himself a lion till he actually sees a lion. Even so, O son of Radha, thou regardest thyself a lion, for thou dost not behold that repressor of foes, that tiger among men, viz., Dhananjaya. Thou regardest thyself a lion till thou beholdest the two Krishnas stationed on the same car like Surya and Candramas. As long as thou dost not hear the twang of Gandiva in great battle, so long art thou able to do what thou pleasest. Beholding Partha, causing the ten points of the compass to resound with the roar of his car and the twang of his bow, and beholding him roaring like a tiger, thou wilt become a jackal. Thou art always a jackal, and Dhananjaya always a lion. O fool, in consequence of thy envy and hatred for heroes, thou always, seemest to be like a jackal. As a mouse and a car are to each other in strength, or a dog and a tiger, a fox and a lion, or a hare and an elephant, as falsehood and truth, as poison and nectar, even so art thou and Partha known to all by your respective deeds."'"
