Mbh 4.60.1a

“Arjuna said, ‘The time, O Karna, hath now come for making good thy loquacious boast in the midst of the assembly, viz., that there is none equal to thee in fight. Today, O Karna, contending with me in terrible conflict, thou shalt know thy own strength, and shalt no longer disregard others. Abandoning good breeding, thou hadst uttered many harsh words, but this that thou endeavourest to do, is, I think, exceedingly difficult. Do thou now, O Radha’s son, contending with me in the sight of the Kurus, make good what thou hadst said before in disregard of myself. Thou who hadst witnessed Panchala’s princess outraged by villains in the midst of the court, do thou now reap the fruit of that act of thine. Fettered by the bonds of morality before, I desisted from vengeance then. Behold now, O son of Radha, the fruit of that wrath in conflict at hand. O wicked wight, we have suffered much misery in that forest for full twelve years. Reap thou today the fruits of our concentrated vengeance. Come, O Karna, cope with me in battle. Let these thy Kaurava warriors witness the conflict.’ Hearing these words, Karna replied, ‘Do thou, O Partha, accomplish in deed what thou sayst in words. The world knows that thy words verily exceed thy deed. That thou hadst foreborne formerly was owing to thy inability to do anything. If we witness thy prowess even now, we may acknowledge its truth. If thy past forbearance was due to thy having been bound by the bonds of morality, truly thou art equally bound now although thou regardest thyself free. Having as thou sayst, passed thy exile in the woods in strict accordance with thy pledge and being therefore weakened by practising an ascetic course of life, how canst thou desire a combat with me now? O Pritha’s son, if Sakra himself fight on thy side, still I would feel no anxiety in putting forth my prowess. Thy wish, O son of Kunti, is about to be gratified. Do thou fight with me now, and behold my strength.’
