Mbh 5.96.1b

And who are they?” And the Brahmanas answered him, saying, “It had been heard by us that those two persons are ascetics called Nara and Narayana. They have both taken their births in the race of man. Go and fight with them, O king. It is that illustrious pair, Nara and Narayana, who are now practising the severest of penances in some hidden region of the mountains of Gandhamadana.” Hearing those words of the Brahmanas, that king speedily mustered his large army consisting of six kinds of forces,[7] and unable to bear their reputation, marched to the spot where those unvanquished ascetics were, and arrived at the rugged and frightful mountains of Gandhamadana. He began to search after those Rishis, and at last, came upon them concealed within the woods. And beholding those two best of persons emaciated with hunger and thirst, their veins swollen and visible, and themselves much afflicted with cold winds, and the hot rays of the sun, he approached them, and touching their feet, enquired after their welfare. And the two Rishis received the king hospitably, with fruits and roots, and a seat and water. And they then enquired after the king’s business, saying, “Let it be done.” And thus addressed by them, the king said unto them the same words that he was in the habit of saying unto all. And he said, “The whole earth has been conquered by the might of my arms. All my foes have been slain. Desiring a battle with you both I have come to this mountain. Offer me this hospitality. I have been cherishing this wish from a long time.” Thus addressed, Nara and Narayana said, “O best of kings, wrath and covetousness have no place in this retreat. How can a battle, therefore, be possible here? There are no weapons here, and nothing of unrighteousness and malice. Seek battle elsewhere. There are many Kshatriyas on earth.”’
