Mahabharata Udyoga Parva Chapter 181:3

Mahabharata Udyoga Parva (Uluka Dutagamana Parva) Chapter 181:3 There, O Rama, where in days of yore thou hadst propitiated thy (deceased) fathers (with oblations of Kshatriya blood), slaying thee there, O son of Bhrigu, I will propitiate the Kshatriya slain by thee! Come there, O Rama, without delay! There, O thou that art difficult of being vanquished, I will curb thy old pride about which the Brahmanas speak! For many long years, O Rama, thou hast boasted, saying,—I have, single-handed, vanquished all the Kshatriyas of the Earth!—Listen now to what enabled thee to indulge in that boast! In those days no Bhishma was born, or no Kshatriyas like unto Bhishma! Kshatriyas really endued with valour have taken their births later on! As regards thyself, thou hast consumed only heaps of straw! The person that would easily quell thy pride of battle hath since been born! He, O mighty-armed one, is no other than myself, even Bhishma, that subjugator of hostile cities! Without doubt, O Rama, I shall just quell thy pride of battle. Bhishma continued, "Hearing these words of mine. Rama addressed me, laughingly saying, 'By good luck it is, O Bhishma, that thou desirest to fight with me in battle! O thou of Kuru's race, even now I go with thee to Kurukshetra! I will do what thou hast said! Come thither, O chastiser of foes! Let thy mother, Jahnavi, O Bhishma, behold thee dead on that plain, pierced with my shafts, and become the food of vultures, crows, and other carnivorous birds! Let that goddess worshipped by Siddhas and Charanas, that blessed daughter of Bhagiratha, in the form of a river, who begat thy wicked self, weep today, O king, beholding thee slain by me and lying miserable on that plain, however undeserving she may be of seeing such a sight! Come, O Bhishma, and follow me, O proud wight, always longing for battle! O thou of Kuru's race, take with thee, O bull of Bharata's line, thy cars and all other equipments of battle!' Hearing these words of Rama that subjugator of hostile towns, I worshipped him with a bend of my head and answered him, saying,—'So be it!' Having said all this, Rama then went to Kurukshetra from desire of combat, and I also, entering our city, represented everything unto Satyavati. Then causing propitiatory ceremonies to be performed (for my victory), and being blessed also by my mother, and making the Brahmanas utter benedictions on me, I mounted on a handsome car made of silver and unto which, O thou of great glory, were yoked steeds white in hue. And every part of that car was well-built, and it was exceedingly commodious and covered on all sides with tiger-skin. And it was equipped with many great weapons and furnished with all necessaries. And it was ridden by a charioteer who was well-born and brave, who was versed in horse-lore, careful in battle, and well-trained in his art, and who had seen many encounters. And I was accoutred in a coat of mail, white in hue, and had my bow in hand. And the bow I took was also white in hue.
