Mbh 8.39.3a

"Sanjaya continued, 'At the conclusion of these words of Karna, Shalya, the ruler of the Madras, desirous of provoking Karna exceedingly, said these words in reply, "When keen-pointed shafts winged with Kanka feathers, shot by Phalguna of mighty arms and impelled from his bow-string and sped with all his energy will seek thee then wilt thou lament thy encounter with that hero. When Partha, called also Savyasaci, taking up his celestial bow, will scorch the (Kuru) army and afflict thee exceedingly with keen shafts, then, O Suta's son, wilt thou repent (of thy folly). As a child lying on the lap of its mother seeks to seize the Moon, even so dost thou from folly seek to vanquish the resplendent Arjuna stationed on his car. In desiring, O Karna, to fight today with Arjuna of keen-edged feats, thou art for rubbing all thy limbs against the keen edges of a trident. This thy challenge of Arjuna, O Suta's son, is like that of a foolish young little deer of activity challenging a huge lion excited with wrath. Do not, O Suta's son, challenge that prince of mighty energy like a fox gratified with meat in the forest challenging the maned monarch of the forest. Do not be destroyed, encountering Arjuna. Thou, O Karna, challengest Dhananjaya, the son of Pritha, even like a hare challenging a mighty elephant with tusks large as plough-shafts, and with the juice issuing out of its mouth and rent cheeks. From folly thou art piercing, with a piece of wood, the black cobra of virulent poison excited to fury within its hole, in desiring to fight with Partha. Endued with little understanding, thou, O Karna, disregarding that lion among men, viz., the son of Pandu, yellest at him, like a jackal that, disregarding a maned lion excited with wrath, yells at him. As a snake, for its own destruction, challenges that foremost of birds, viz., Vinata's son, possessed of beautiful plumage and great activity, even so dost thou, O Karna, challenge Dhananjaya the son of Pandu.
