Mbh 1.190.2b

One should never disregard a Brahmana whether his acts be right or wrong, by supposing him incapable of achieving any task that is great or little, or that is fraught with bliss or woe. Rama the son of Jamadagni defeated in battle, all the Kshatriyas. Agastya by his Brahma energy drank off the fathomless ocean. Therefore, say ye, ‘Let this youth bend the bow and string it with ease’ (and many said), ‘So be it.’ And the Brahmanas continued speaking unto one another these and other words. Then Arjuna approached the bow and stood there like a mountain. And walking round that bow, and bending his head unto that giver of boons--the lord Isana--and remembering Krishna also, he took it up. And that bow which Rukma, Sunitha, Vakra, Radha’s son, Duryodhana, Salya, and many other kings accomplished in the science and practice of arms, could not even with great exertion, string, Arjuna, the son of Indra, that foremost of all persons endued with energy and like unto the younger brother of Indra (Vishnu) in might, strung in the twinkling of an eye. And taking up the five arrows he shot the mark and caused it to fall down on the ground through the hole in the machine above which it had been placed. Then there arose a loud uproar in the firmament, and the amphitheatre also resounded with a loud clamour. And the gods showered celestial flowers on the head of Partha the slayer of foes. And thousands of Brahmanas began to wave their upper garments in joy. And all around, the monarchs who had been unsuccessful, uttered exclamations of grief and despair. And flowers were rained from the skies all over the amphitheatre. And the musicians struck up in concert. Bards and heralds began to chant in sweet tones the praises (of the hero who accomplished the feat). And beholding Arjuna, Drupada--that slayer of foes,--was filled with joy. And the monarch desired to assist with his forces the hero if the occasion arose.
