Mbh 8.49.1e

Then Shalya addressed him, and said, "Do not, O Karna, seize this best of kings. As soon as thou seizest him, he will reduce both thee and me to ashes." Then Karna, O king, laughing in mockery, addressed the son of Pandu and thus spoke unto him disparagingly. "How, indeed, born though thou art in a noble race, and observant though thou art of Kshatriya duties, wouldst thou leave the battle in fear, desiring to save thy life? I think that thou art not well-acquainted with the duties of Kshatriyas. Endued with Brahma-force, thou art indeed devoted to the study of the Vedas and the performance of sacrificial rites. Do not, O son of Kunti, fight again, and do not again approach brave warriors. Do not use harsh language towards heroes and do not come to great battles. Thou mayst use such words, O sire, towards others, but thou shouldst never address persons like us in that way. By using such words towards persons like us, thou wouldst in battle meet with this and other kinds of behaviour. Go back to thy quarters, O son of Kunti, or thither where those two, viz., Keshava and Arjuna, are. Indeed, O king, Karna will never slay one like thee." Having said these words unto the son of Pritha, the mighty Karna, setting Yudhishthira free, began to slaughter the Pandava host like the wielder of the thunderbolt slaughtering the Asura host. That ruler of men, (viz., Yudhishthira,) then, O king, quickly fled away. Beholding the king flying away, the Cedis, the Pandavas, the Pancalas, and the mighty car-warrior Satyaki, all followed that monarch of unfading glory. And the sons of Draupadi, and the Suras, and the twin sons of Madri by Pandu, also followed the king. Beholding the division of Yudhishthira retreating, the heroic Karna became highly glad with all the Kurus and began to pursue the retreating force. The din of battle-drums and conchs and cymbals and bows, and leonine shouts, arose from among the Dhartarashtra troops.
