Mbh 7.126.2a

“Sanjaya said, ‘Having said those words, the mighty Bhima began to prepare for setting out, repeatedly making over Yudhishthira to Dhrishtadyumna and the other friends (of the Pandava cause). Indeed, Bhimasena of mighty strength addressing Dhrishtadyumna, said, “It is known to thee, O thou of mighty arms, how the mighty car-warrior Drona is always on the alert to seize king Yudhishthira the Just by all means in his power. Indeed, O son of Prishata, I should never place my going (to Arjuna and Satyaki) above my duty of protecting the king. King Yudhishthira, however, hath commanded me to go, I dare not contradict him. I shall go thither where the ruler of the Sindhus stayeth, at the point of death. I should, in complete truthfulness, act according to the words of my brother (Arjuna) and of Satyaki endued with great intelligence. Thou shouldst, therefore, vigorously resolved on fight, protect Yudhishthira the son of Pritha today. Of all tasks, this is thy highest duty in battle.” Thus addressed by Vrikodara, O monarch, Dhrishtadyumna replied, “I shall do what thou wishest. Go, O son of Pritha, without any anxiety of the kind. Without slaying Dhrishtadyumna in battle, Drona will never be able to humiliate king Yudhishthira in the fight.” Thus making the royal son of Pandu over to Dhrishtadyumna, and saluting his elder brother, Bhimasena, proceeded towards the spot where Phalguna was. Before dismissing him, however, king Yudhishthira the Just, O Bharata, embraced Bhimasena and smelt his head and pronounced auspicious blessings upon him. After circumambulating a number of Brahmanas, gratified with worship and presents, and touching the eight kinds of auspicious articles, and quaffing Kairataka honey, that hero, the corners of whose eyes had become red in intoxication, felt his might to be doubled. The Brahmanas performed propitiatory ceremonies for him. Various omens, indicative of success, greeted him. Beholding them, he felt the delight of anticipated victory.
