Mbh 7.111.2b

And the hero then, with joined hands, worshipped the feet of Yudhishthira, and the latter smelt his head. And having undergone all these rites, he then mounted his foremost of cars. Then those steeds, cheerful and strong and fleet as the wind, and invincible, and belonging to the Sindhu breed, bore him on that triumphant car. Similarly, Bhimasena also, honoured by king Yudhishthira the just, and reverentially saluting the monarch, set out with Satyaki. Beholding those two chastisers of foes on the point of penetrating thy host, their enemies, viz., thy troops, all stood still with Drona at their head. Then Satyaki, seeing Bhima cased in mail and following him, saluted that hero and spoke unto him these delightful words. Indeed, heroic Satyaki, with every limb filled with joy, said unto Bhima, “Do thou, O Bhima, protect the king. Even this is thy duty above all things. Piercing through this host whose hour hath come, I will proceed. Whether now or hence, the protection of the king is thy highest duty. Thou knowest my prowess, thou desirest my good, return, O Bhima!” Thus addressed by Satyaki, Bhima replied, “Go then, for the success of thy object. O best of men, I will protect the king.” Thus addressed, he of Madhu’s race answered Bhima, saying, “Go back, O son of Pritha! My success is certain, since won over by my merits, thus, O Bhima, art today obedient to my wishes. Indeed, O Bhima, as these auspicious omens tell me, my victory is assured. After the sinful ruler of the Sindhus has been slain by the high-souled son of Pandu, I shall embrace king Yudhishthira of virtuous soul.” Having said these words unto Bhima and dismissing him with an embrace that illustrious warrior eyed thy troops, like a tiger eyeing a herd of deer. Beholding him thus looking at thy army, O king, thy troops become once more stupefied and began to tremble violently.
