RV 3.5.4
मित्रो अग्निर् भवति यत् समिद्धो मित्रो होता वरुणो जातवेदाः । मित्रो अध्वर्युर् इषिरो दमूना मित्रः सिन्धूनाम् उत पर्वतानाम् ॥
mitro agnir bhavati yat samiddho mitro hotā varuṇo jātavedāḥ | mitro adhvaryur iṣiro damūnā mitraḥ sindhūnām uta parvatānām ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni is Mitra when enkindled duly, Mitra as Priest, Varuna, Jatavedas; Mitra as active minister, and House-Friend, Mitra of flowing rivers and of mountains.
Translated by Ralph T. H. Griffith (1896)
