Mahabharata Drona Parva Chapter 159:2

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 159:2 Thus addressed by him, all those combatants, O king, poured showers of weapons upon Drona's son like clouds pouring torrents of rain. Baffling that shower, Drona's son in that battle, slew ten brave warriors amongst them, in the very sight, O lord, of Dhrishtadyumna and the sons of Pandu. The Panchalas and the Somakas then, thus worked in battle, abandoned the son of Drona and fled away in all directions. Beholding those brave warriors, viz., the Panchalas and the Somakas, flying away, Dhrishtadyumna, O king, rushed against Drona's son in that battle. Surrounded then by a hundred brave and unreturning car-warriors mounted upon cars, decked with gold, and the rattle of whose wheels resembled the roar of rain-charged clouds, the mighty car-warrior Dhrishtadyumna, the son of the Panchala king, beholding his warriors slain, addressed Drona's son and said these words, "O foolish son of the preceptor, what is the use of slaying vulgar combatants. If thou art a hero, fight then with me in battle. I will slay thee. Wait for a moment without flying away." Saying thus, Dhrishtadyumna of great prowess struck the preceptor's son with many keen and terrible arrows capable of piercing the very vitals. Those swiftly-coursing shafts, equipped with golden wings and keen points, and capable of piercing the body of every foe proceeding in a continuous line, penetrated into Aswatthaman's body, like freely-roaming bees in search of honey entering a flowering tree. Deeply pierced and swelling with rage, like a trodden snake, the proud and fearless son of Drona, arrow in hand, addressed his foe, saying, "O Dhrishtadyumna, wait for moment, without leaving my presence. Soon shall I despatch thee to Yama's abode with my keen shafts." Having said these words, that slayer of hostile heroes, viz., the son of Drona, displaying great lightness of hands, covered the son of Prishata from every side with clouds of arrows. Thus covered in that encounter (with arrows) by Drona's son, the Panchala prince, difficult to defeat in battle, said "Thou knowest not of my origin, O Brahmana, or of my vow. O thou of wicked understanding, having first slain Drona himself, I will not, therefore, slay thee today when Drona himself is still alive. O thou of wicked understanding, after this night passeth away and bringeth in the fair dawn, I shall first slay thy sire in battle and then despatch thee also to the region of Spirits. Even this is the wish entertained by me. Standing before me, display, therefore, till then, the hatred thou bearest towards the Parthas, and the devotion thou cherishest for the Kurus. Thou shalt not escape from me with life. That Brahmana who, abandoning the practices of a Brahmana, devoteth himself to the practices of a Kshatriya, becomes slayable by all Kshatriyas even as thou, O lowest of men." Thus addressed by Prishata's son in language so harsh and insulting that best of Brahmanas Aswatthaman mustered all his rage and answered, saying, "Wait, Wait!" And he gazed at Prishata's son apparently burning him with his eyes.
