The food supplied by Vidura alone, should, I think, be eaten by me.'
Other people also came.
Having said this unto Duryodhana who was ever incapable of bearing anything against his own wishes, Kesava of mighty arms then came out of that blazing palace of Dhritarashtra's son. And the high-souled Vasudeva of mighty arms, coming out of that mansion, directed his steps towards the abode of the illustrious Vidura. And while that mighty-armed one staying within Vidura's abode, thither came unto him Drona, and Kripa, and Bhishma, and Vahlika, and many of the Kauravas. And the Kauravas that came there addressed Madhava, the heroic slayer of Madhu, saying, 'O thou of Vrishni's race, we place at thy disposal our houses with all the wealth within them.'
But Krishna refused them.
'The slayer of Madhu, of mighty energy, answered them saying, 'Ye may go away. I am much honoured by these your offers.'
Krishna was entertained and gratified by Vidura.
And after all the Kurus had gone away, Vidura, with great care entertained that unvanquished hero of Dasarha's race with every object of desire. And Kunti then placed before the illustrious Kesava clean and savoury food in abundance. Therewith the slayer of Madhu first gratified the Brahmanas. Indeed, from that food he first gave a portion, along with much wealth, unto a number of Brahmanas conversant with the Vedas, and then with his attendants, like Vasava in the midst of the Marutas, he dined on what remained of the clean and savoury food supplied by Vidura.'"
Krishna also explained why he cannpt expect Duryodhana's offers.

"Vaisampayana continued, 'Thus addressed by the king, Janardana of Dasarha's race, casting his eyes on Dhritarashtra's son and ah his counsellors, replied, saying, 'Not from desire, nor from wrath, nor from malice, nor for gain, nor for the sake of argument, nor from temptation, would I abandon virtue. One taketh another's food when one is in distress. At present, however, O king, thou hast not inspired love in me by any act of thine, nor have I myself been plunged into distress. Without any reason, O king, thou hatest, from the moment of their birth, thy dear and gentle brothers,--the Pandavas--endued with every virtue. This unreasonable hatred of thine for the sons of Pritha ill becometh thee. The sons of Pandu are all devoted to virtue. Who, indeed, can do them the least injury? He that hateth them, hateth me; he that loveth them, loveth me. Know that the virtuous Pandavas and my own self have but a common soul. He, who, following the impulses of lust and wrath, and from darkness of soul, hateth and seeketh to injure one that is possessed of every good quality, is regarded as the vilest of men. That wrathful wretch of every good quality, is regarded as the vilest of men. That wrathful wretch of uncontrolled soul, who, from ignorance and avarice hateth his kinsmen endued with every auspicious quality, can never enjoy his prosperity long. He, on the other hand, who, by good offices, winneth over persons endued with good qualities, even if he beareth aversion of them within his heart, enjoyeth prosperity and fame for ever and ever. Defiled by wickedness, all this food, therefore, deserveth not to be eaten by me.
