Mbh 5.10.3a

“Salya continued, ‘When he had thus spoken, the Rishis and the celestials placed Indra at their head, and uniting together, went away. Approaching Indra they beheld Vritra glowing and resplendent as if scorching the ten points, and swallowing all the three worlds, and resembling the sun or the moon. And then the Rishis, came up to Vritra and spoke to him in conciliatory terms, saying, “O thou unconquerable being, the whole of this universe hath been pervaded by thy energy. Thou art not able however to overpower Indra, O best of mighty beings. A long period hath now elapsed since you began to fight. All beings, with the gods and the Asuras and men, are suffering from the effects of the fight. Let there be eternal friendship between thee and Indra. Thou shalt be happy and shall dwell eternally in Indra’s regions.” And the mighty Vritra having heard the words of the saints, bowed his head unto them. And the Asura (thus) spoke, “What you, O highly-gifted beings, and also all these Gandharvas are saying, I have heard. Ye stainless beings, hear also what I have got to say. How can there be peace between us two, Indra and myself? How can there be friendship, ye gods, between two hostile powers?” The Rishis said, “Friendship among righteous persons happens at a single meeting. It is a desirable object. Thereafter will happen what is fated to be. The opportunity of forming friendship with a righteous person should not be sacrificed. Therefore, the friendship of the righteous should be sought. The friendship of the righteous is (like) excellent wealth, for he that is wise would give advice when it is needed. The friendship of a good person is of great use; therefore, a wise person should not desire to kill a righteous one. Indra is honoured by the righteous, and is the refuge of magnanimous persons, being veracious and unblamable, and knows what virtue is, and is possessed of a refined judgment. Let there be eternal friendship between thee and Indra, as described above.
