Mbh 5.50.6a

Vaisampayana continued, “Having recovered consciousness, and being comforted, Sanjaya addressed king Dhritarashtra in the midst of that concourse of Kurus in that hall, saying, ‘Indeed, O king of kings, I saw those great warriors, the sons of Kunti, thinned in body, in consequence of the restraint in which they had lived in the place of the king of the Matsyas. Hear, O King, with whom the Pandavas will contend against you. With that hero Dhrishtadyumna as their ally, they will fight against you. With that personage of virtuous soul, who never forsaketh truth through anger or fear, temptation, or for the sake of wealth, of disputation; and who is, O King, a very authority in matters of religion, himself being the best of those that practise virtue;--with him, who hath never made an enemy, the sons of Pandu will fight against you. He unto whom no one on earth is equal in might of arms, and who, wielding his bow had brought all kings under subjection, and who, vanquishing of old all the people of Kasi and Anga and Magadha, as also the Kalingas;--with that Bhimasena will the sons of Pandu fight against you. Indeed, he through whose might the four sons of Pandu quickly could alight on the earth, having issued forth from the (burning) house of lac that son of Kunti, Vrikodara, who became the means of their rescue from the cannibal Hidimva; that son of Kunti, Vrikodara, who became their refuge when the daughter of Yajnasena was being carried away by Jayadratha; indeed, with that Bhima who rescued the assembled Pandavas from the conflagration at Varanavata; even with him (as their ally) will they fight against you. He, who for the gratification of Krishna slew the Krodhavasas, having penetrated the rugged and terrible mountains of Gandhamadana, he to whose arms hath been imparted the might of ten thousand elephants; with that Bhimasena (as their ally) the Pandavas will fight against you.
