Mbh 5.22.1c

The chief of the Somaka tribe, with his followers, is, I have heard, so devoted to the cause of the Pandavas that he is ready to lay down his very life for them. Who would be able to withstand Yudhishthira who hath the best of the Vrishni tribe (Krishna) for his leader? I have heard that Virata, the chief of the Matsyas, with whom the Pandavas had lived for some time and whose wishes were fulfilled by them, old in years, is devoted, along with his sons to the Pandava cause, and hath become an adherent of Yudhishthira. Deposed from the throne of the Kekaya land, and desirous of being reinstated thereon, the five mighty brothers from that land, wielding mighty bows, are now following the sons of Pritha ready to fight. All who are valiant among the lords of the earth have been brought together and are devoted to the Pandava cause. I hear that they are bold, worthy, and respectful,--they who have allied themselves to the virtuous king Yudhishthira from feelings of attachment to him. And many warriors dwelling on the hills and inaccessible fastnesses, and many that are high in lineage and old in years, and many Mleccha tribes also wielding weapons of various kinds, have been assembled together and are devoted to the cause of the Pandavas. And there hath come Pandya also, who, hardly inferior to Indra on the field of battle, is followed when he fights by numberless warriors of great courage. Remarkably heroic and endued with prowess and energy that have no parallel, he is devoted to the Pandava cause. That same Satyaki who, I have heard, obtained weapons from Drona and Arjuna and Krishna and Kripa and Bhishma, and who is said to be equal to the son of Krishna, is devotedly attached to the Pandava cause. And the assembled kings of the Chedi and the Karusha tribes have all taken the part of the Pandavas with all their resources.
