Mbh 6.108.2

“Hearing these words of Krishna, Yudhishthira said, ‘It is even so, O thou of mighty arms, even as thou sayest, O thou of Madhu’s race. All these together are not competent to bear thy force. I am sure of always having whatever I desire, when, O tiger among men, I have thyself staying on my side. O foremost of victorious persons, I would conquer the very gods with Indra at their head, when, O Govinda, I have thee for my protector. What need I say, therefore, of Bhishma, though he is a mighty car-warrior? But, O Krishna, I dare not, for my own glorification, falsify thy words. Therefore, O Madhava, as promised before by thee, render me aid without fighting for me. In this battle an agreement was made by me with Bhishma. He said,--“I will give thee counsel, but fight I shall never for thee, since I shall have to fight for Duryodhana’s sake.” Know this for truth. Therefore, O Lord, Bhishma may give me sovereignty by giving me good counsel, O Madhava. Therefore, O slayer of Madhu, all of us accompanied by thee, will once more repair unto Devavrata, for asking him about the means of his own death. All of us then, O best of persons, together going to Bhishma without delay, will speedily ask him of Kuru’s race his advice. O Janardana, he will truly give us beneficial counsel; and O Krishna, I will do in battle what he will say. Of austere vows, he will give us counsel, as also victory. We were children and orphans. By him were we reared. O Madhava, him, our aged grandsire, I wish to day,--him, the sire of our sire. Oh, fie upon the profession of a Kshatriyas.’”
