Mbh 3.172.2b

And battered and broken by the straight-coursing iron shafts, shot by me, the city of the Asuras, O king, fell to the earth. And they also, wounded by my iron arrows having the speed of the thunder, began, O monarch, to go about, being urged by destiny. Then ascending to the sky, Matali, as if falling in front, swiftly descended to the earth, on that chariot of solar resplendence. Then, O Bharata, environed me sixty thousand cars belonging to those wrathful ones eager to battle with me. And with sharpened shafts graced with feathers of the vulture, I destroyed those (cars). At this, thinking, ‘These our hosts are incapable of being vanquished by mortals, they became engaged in the conflict, like unto the surges of the sea.’ Thereupon I gradually began to fix (on the string) unearthly weapons. At this, thousands of weapons (shot) by those wonderfully warring charioteers, by degrees opposed my unearthly arms and in the field I saw hundreds and thousands of mighty (demons) ranging on their cars, in various manoeuvres. And being furnished with variegated mail and standards and diverse ornaments, they delighted my mind. And in the conflict I could not afflict them by showers of shafts, but they did not afflict me. And being afflicted by those innumerable ones, equipped in weapons and skilled in fight, I was pained in that mighty encounter and a terrible fear seized me. Thereupon collecting (my energies) in fight, I (bowed down) unto that god of gods, Raudra, and saying, ‘May welfare attend on all beings!’ I fixed that mighty weapon which, celebrated under the name of Raudra, is the destroyer of all foes. Then I beheld a male person having three heads, nine eyes, three faces, and six arms. And his hair was flaming like fire or the sun. And, O slayer of foes, for his dress, he had mighty serpents, putting out their tongues.
