Mbh 5.7.2

Vaisampayana continued, “Thus addressed by Krishna, Dhananjaya the son of Kunti selected Kesava who was not to fight on the battle-field, even Narayana himself, the slayer of foes, increate, born among men at his own will,--the foremost of all Kshatriyas and above all the gods and the Danavas. And Duryodhana selected for himself that entire army (composed of the Narayanas). And, O descendant of Bharata, having obtained those troops numbering thousands upon thousands, he was exceedingly delighted, although he knew that Krishna was not on his side. And having secured that army possessed of terrible prowess, Duryodhana went to the son of Rohini of great strength, and explained to him, the object of his visit. The descendant of Sura in reply addressed the following words to Dhritarashtra’s son, ‘Thou shouldst remember, O tiger among men, all that I said at the marriage ceremony celebrated by Virata. O thou delighter of the race of Kuru, for thy sake I then contradicted Krishna and spoke against his opinions. And again and again I alluded to the equality of our relationship to both the parties. But Krishna did not adopt the views I then expressed; nor can I separate myself from Krishna for even a single moment. And seeing that I cannot act against Krishna even this is resolution formed by me, viz., that I will fight neither for Kunti’s sons nor for you. And, O bull of the Bharatas, born as thou art in Bharata’s race that is honoured by all the kings, go and fight in accordance with the rules of propriety.’”
