Mbh 7.17.2a

“Sanjaya continued, ‘Hearing those words of Drona, the ruler of the Trigartas, O monarch, with his brothers, said these words: “We, O king, are always humiliated by the wielder of Gandiva! O bull of Bharata’s race, although we have done him no injury, yet he hath always injured us. Remembering all those diverse instances of humiliation, we burn in wrath and are never able to sleep at night. By good luck, that Arjuna, armed with weapons, will stand before us. That therefore, which is in our heart and which we strive to accomplish, we are resolved to achieve now, that viz., which will be agreeable to thee, and which will bring us renown. Taking him out of the field will slay him. Let the earth today be without Arjuna or let it be without the Trigartas. We truly swear this before thee. This our vow will never be false.” And Satyaratha and Satyavarman, O Bharata, and Satyavrata and Satyeshu, and Satyakarman also, having spoken similarly, those five brothers together, with ten thousand cars, came, O king, (before Duryodhana), having taken that oath on the field of battle. And the Malavas, and the Tundikeras with thousand cars, and the tiger among men, Susarman, the ruler of Prasthala, with the Mavellakas, the Lalithas, and the Madrakas, accompanied by ten thousand cars and his brothers, and with another ten thousand cars from diverse realms came forward for taking the oath. Then bringing fire, and each making preparations for igniting one for himself, they took up ropes Kusa grass and beautiful coats of mail.
