Mbh 12.132.2a

"'Bhishma said, "When such a time sets in, the Brahmana should live by the aid of knowledge. Everything in this world is for them that are good. Nothing here is for them that are wicked. He who making himself an instrument of acquisition, takes wealth from the wicked and gives it unto them that are good, is said to be conversant with the morality of adversity. Desirous of maintaining his rule, the king, O monarch, without driving his subjects to indignation and rebellion, may take what is not freely given by the owner, saying, 'This is mine!' That wise man who, cleansed by the possession of knowledge and might and of righteous conduct at other times, acts censurably in such season, does not really deserve to be censured. They who always support themselves by putting forth their might never like any other method of living. They that are endued with might, O Yudhishthira, always live by the aid of prowess. The ordinary scriptures, that exist (for seasons of distress) without exceptions of any kind, should be practised by a king (at such times). A king, however, that is endued with intelligence, while following those scriptures, would do something more.[398] At such times, however, the king should not oppress Ritwijas, and Purohitas and preceptors and Brahmanas, all of whom are honoured and held in high esteem. By oppressing them, even at such times, he incurs reproach and sin. This that I tell thee is regarded as an authority in the world. Indeed, this is the eternal eye (by which practices in seasons of distress are to be viewed). One should be guided by this authority. By this is to be judged whether a king is to be called good or wicked. It is seen that many persons residing in villages and towns, actuated by jealousy and wrath, accuse one another. The king should never, at their words, honour or punish anybody. Slander should never be spoken. If spoken, it should never be heard.
