Mbh 2.73.3a

‘Hast thou not heard, O king, what the learned Vrihaspati the preceptor of the celestials, said in course of counselling Sakra about mortals and politics? Even these, O slayer of foes, were the words of Vrihaspati, ‘Those enemies that always do wrong by stratagem or force, should be slain by every means.’ If, therefore, with the wealth of the Pandavas, we gratify the kings of the earth and then fight with the sons of Pandu, what reverses can overtake us? When one hath placed on the neck and back of venomous snakes full of wrath for encompassing his destruction, is it possible for him to take them off? Equipped with weapon and seated on their cars, the angry sons of Pandu like wrathful and venomous snakes will assuredly annihilate us, O father. Even now Arjuna proceedeth, encased in mail and furnished with his couple of quivers, frequently taking up the Gandiva and breathing hard and casting angry glances around. It hath (also) been heard by us that Vrikodara, hastily ordering his car to be made ready and riding on it, is proceeding along, frequently whirling his heavy mace. Nakula also is going along, with the sword in his grasp and the semi-circular shield in his hand. And Sahadeva and the king (Yudhishthira) have made signs clearly testifying to their intentions. Having ascended their cars that are full of all kinds of arms, they are whipping their horses (for going to Khandava soon) and assembling their forces. Persecuted thus by us they are incapable of forgiving us those injuries. Who is there among them that will forgive that insult to Draupadi? Blest be thou. We will again gamble with the son of Pandu for sending them to exile. O bull among men, we are competent to bring them thus under our sway. Dressed in skins, either we or they defeated at dice, shall repair to the woods for twelve years. The thirteenth year shall have to be spent in some inhabited country unrecognised; and, if recognised, an exile for another twelve years shall be the consequence.
