Mbh 8.31.5a

"'When the night dawned, Karna repaired to king Duryodhana. Approaching the king, the mighty-armed hero said, "I shall, O king, engage in battle today the illustrious son of Pandu. Either I will slay that hero today, or he will slay me. In consequence of the diverse things both myself and Partha had to do, O Bharata, an encounter, O king, could not hitherto take place between myself and Arjuna! Listen now, O monarch, to these words of mine, spoken according to my wisdom. Without slaying Partha in battle I will not come back, O Bharata. Since this army of ours hath been deprived of its foremost warriors, and since I will stand in battle, Partha will advance against me, especially because I am destitute of the dart Sakra gave me. Therefore, O ruler of men, listen now to what is beneficial. The energy of my celestial weapons is equal to the energy of Arjuna's weapons. In counteracting the feats of powerful foes, in lightness of hands, in range of the arrows shot, in skill, and in hitting the mark, Savyasaci is never my equal. In physical strength, in courage, in knowledge of (weapons), in prowess, O Bharata, in aiming, Savyasaci is never my equal. My bow, called Vijaya, is the foremost of all weapons (of its kind). Desirous of doing what was agreeable (to Indra), it was made by Viswakarman (the celestial artificer) for Indra. With that bow, O king, Indra had vanquished the Daityas. At its twang the Daityas beheld the ten points to be empty. That bow, respected by all, Sakra gave to Bhrigu's son (Rama). That celestial and foremost of bows Bhrigu's son gave to me. With that bow I will contend in battle with the mighty-armed Arjuna, that foremost of victorious warriors, like Indra fighting with the assembled Daityas. That formidable bow, the gift of Rama, is superior to Gandiva. It was with that bow that the Earth was subjugated thrice seven times (by Bhrigu's son). With that bow given to me by Rama I will contend in battle with the son of Pandu.
