Srimad Bhagavatam Canto 03, Chapter 20, Text 02

SB 3.20.2

ksatta maha-bhagavatah
 krsnasyaikantikah suhrt
yas tatyajagrajam krsne
 sapatyam aghavan iti
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Saunaka Rsi inquired about Vidura, who was a great devotee and friend of Lord Krsna and who gave up the company of his elder brother because the latter, along with his sons, played tricks against the desires of the Lord.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The incident referred to here is that Vidura left the protection of his elder brother Dhrtarastra, went traveling everywhere to sacred places and met Maitreya at Hardwar. Saunaka Rsi here inquires about the topics of the conversation between Maitreya Rsi and Vidura. Vidura’s qualification was that he was not only a friend of the Lord but also a great devotee. When Krsna tried to stop the war and mitigate the misunderstanding between the cousin-brothers, they refused to accept His counsel; therefore Ksatta, or Vidura, was unsatisfied with them, and he left the palace. As a devotee, Vidura showed by example that anywhere that Krsna is not honored is a place unfit for human habitation. A devotee may be tolerant regarding his own interests, but he should not be tolerant when there is misbehavior toward the Lord or the Lord’s devotee. Here the word aghavan is very significant, for it indicates that the Kauravas, Dhrtarastra’s sons, lost the war because of being sinful in disobeying the instructions of Krsna.
