Mbh 8.86.2

"'Arjuna said, "My victory, O Krishna, is certain. There is no doubt in this, since thou, O slayer of Madhu, that art the master of all the worlds, art pleased with me. Urge the steeds, O Hrishikesha, and my car, O great car-warrior! Today Phalguna will not return from battle without slaying Karna. Behold Karna slain today and cut in pieces with my shafts. Or, O Govinda, thou wilt today behold me slain with (Karna's) arrows. That terrible battle, capable of stupefying the three worlds, is at hand. As long as the earth will last, people will speak of it." Saying these words unto Krishna who is never tired with exertion, Partha quickly proceeded on his car against Karna like an elephant against a rival elephant. Once more Partha of great energy said unto Krishna, that chastiser of foes, these words, "Urge the steeds, O Hrishikesha, for time passeth." Thus addressed by the high-souled son of Pandu, Keshava wished him victory and urged steeds as fleet as thought. Then that car of Pandu's son, possessed of great speed, soon reached the front of Karna's car.'"
