Mbh 8.70.4a

"Sanjaya said, 'Having said these words unto that foremost of virtuous persons, viz., Yudhishthira, Partha threw down his weapons and cast aside his bow and quickly thrust his sword back into its sheath. Hanging down his head in shame, the diadem-decked Arjuna, with joined hands, addressed Yudhishthira, and said, "Be cheerful, O king, forgiving me. What I have said, you will understand a little while after. I bow to thee." Thus seeking to cheer that royal hero capable of bearing all foes, Arjuna, that foremost of men, standing there, once more said, "This task will not be delayed. It will be accomplished soon. Karna cometh towards me. I shall proceed against him. I shall, with my whole soul, proceed for rescuing Bhima from the battle and for slaying the Suta's son. I tell thee that I hold my life for thy good. Know this for the truth, O king." Having said so, the diadem-decked Arjuna of blazing splendour touched the king's feet and rose for proceeding to the field. Hearing, however, those harsh words of his brother Phalguna, Pandu's son, king Yudhishthira, the just, rising up from that bed (on which he had been sitting), said these words unto Partha, with his heart filled with sorrow, "O Partha, I have acted wickedly. For that, ye have been overwhelmed with terrible calamity. Do thou strike off, therefore, this my head today. I am the worst of men, and the exterminator of my race. I am a wretch. I am addicted to wicked courses. I am of foolish understanding. I am idle and a coward. I am an insulter of the old. I am cruel. What wouldst thou gain by always being obedient to a cruel person like me? A wretch that I am, I shall this very day retire into the woods. Live you happily without me. The high-souled Bhimasena is fit to be king. A eunuch that I am, what shall I do with sovereignty? I am incapable of bearing these harsh speeches of thee excited with wrath. Let Bhima become king. Having been insulted thus, O hero, what use have I with life."
