Mbh 1.227.2a

“Vaisampayana, said, ‘Thus addressed by Arjuna, the smoke-bannered Hutasana, desirous of an interview with Varuna, recollected that son of Aditi,--that deity protecting one of the points of the heavens and having his home in the water and ruling that element. Varuna, knowing that he was thought of by Pavaka, immediately appeared before that deity. The smoke-bannered celestial welcoming with reverence the ruler of the waters, that fourth of the Lokapalas, said unto that eternal god of gods, ‘Give me without loss of time that bow and quiver, and that ape-bannered car also, which were obtained from king Soma. Partha will achieve a great task with Gandiva, and Vasudeva also with the discus! Give both, therefore, unto me today.’ Hearing these words, Varuna replied unto Pavaka, saying, ‘Well, I am giving them.’ He then gave that wonderful jewel of a bow that was endued with great energy. That bow was the enhancer of fame and achievements, and was incapable of being injured by any weapon. It was the chief of all weapons, and the grinder of them all. And it was the smiter of hostile armies and was alone equal to a hundred thousand bows. It was the multiplier of kingdoms, and was variegated with excellent colours. It was well-adorned, and beautiful to behold, and without a mark of weakness or injury anywhere. And it was always worshipped both by the celestials and the Gandharvas. Varuna also gave two inexhaustible quivers, and he also gave a car furnished with celestial weapons and whose banner bore a large ape. Yoked unto that car were steeds white as silver of the fleecy clouds, and born in the region of the Gandharvas, and decked with golden harness, and resembling in fleetness the wind or the mind. And it was equipped with implement of war, and was incapable of being vanquished by the celestials or the Asuras. Its splendour was great and the sounds of its wheels was tremendous. It delighted the heart of every creature that looked at it.
