RV 3.6.5
व्रता ते अग्ने महतो महानि तव क्रत्वा रोदसी आ ततन्थ । त्वं दूतो अभवो जायमानस् त्वं नेता वृषभ चर्षणीनाम् ॥
vratā te agne mahato mahāni tava kratvā rodasī ā tatantha | tvaṃ dūto abhavo jāyamānas tvaṃ netā vṛṣabha carṣaṇīnām ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Great are the deeds of thee, the Great, O Agni: thou by thy power hast spread out earth and heaven. As soon as thou wast born thou wast an envoy, thou, Mighty One, was Leader of the people.
Translated by Ralph T. H. Griffith (1896)
