Mbh 8.46.5a

"Sanjaya continued, 'Thus addressed by Yudhishthira the just, Dhananjaya saying, "So be it," ordered his troops (to do the needful) and himself proceeded to the head of the army. That car for which the Leader of the universe, viz., Agni, who derives his effulgence from Brahman, became the steeds, that car which was known amongst the gods as belonging to Brahman because it sprang first from Brahman himself, that car which in days of old had successively borne Brahman and Ishana and Indra and Varuna one after another, riding on that primeval car, Keshava and Arjuna now proceeded to battle. Beholding that advancing car of wonderful aspect, Shalya once more said unto Adhiratha's son, that warrior of great energy in battle, these words "Yonder comes that car having white steeds yoked unto it and owning Krishna for its driver, that vehicle incapable of being resisted by all the troops, like the inevitable fruit of work. There comes the son of Kunti, slaughtering his foes along the way,--he, that is, about whom thou hadst been enquiring. Since tremendous is the uproar that is being heard, deep as the roar of the clouds, it is, without doubt, those high-souled ones, viz., Vasudeva and Dhananjaya. Yonder ascends a cloud of dust that overspreads the welkin like a canopy. The whole Earth, O Karna, seems to tremble, cut deep by the circumference of Arjuna's wheels. These violent winds are blowing on both sides of thy army. These carnivorous creatures are yelling aloud and these animals are uttering fearful cries. Behold, O Karna, the terrible and portentous Ketu of vapoury form, making the hair to stand on end, hath appeared, covering the Sun. Behold, diverse kinds of animals, all around in large packs, and many mighty wolves and tigers are looking at the Sun. Behold those terrible Kankas and those vultures, assembled together in thousands, sitting with faces towards one another, in seeming discourse. Those coloured yak-tails attached to thy great car are waving unquietly.
