Mbh 1.151.2

“Vaisampayana said, ‘About this time, the learned Vidura had sent into those woods a man of pure character and much trusted by him. This person going to where he had been directed, saw the Pandavas with their mother in the forest employed in a certain place in measuring the depth of a river. The design that the wicked Duryodhana had formed had been, through his spies, known to Vidura of great intelligence, and, therefore, he had sent that prudent person unto the Pandavas. Sent by Vidura unto them, he showed the Pandavas on the sacred banks of the Ganga a boat with engines and flags, constructed by trusted artificers and capable of withstanding wind and wave and endued with the speed of the tempest or of thought. He then addressed the Pandavas in these words to show that he had really been sent by Vidura, ‘O Yudhishthira, he said, “listen to these words the learned Vidura had said (unto thee) as a proof of the fact that I come from him. Neither the consumer of straw and the wood nor the drier of dew ever burneth the inmates of a hole in the forest. He escapeth from death who protecteth himself knowing this, etc.’ By these credentials know me to be the person who has been truly sent by Vidura and to be also his trusted agent. Vidura, conversant with everything, hath again said, ‘O son of Kunti, thou shalt surely defeat in battle Karna, and Duryodhana with his brothers, and Sakuni.’ This boat is ready on the waters, and it will glide pleasantly thereon, and shall certainly bear you all from these regions!’
