RV 6.15.4
द्युतानं वो अतिथिं स्वर्णरम् अग्निं होतारम् मनुषः स्वध्वरम् । विप्रं न द्युक्षवचसं सुवृक्तिभिर् हव्यवाहम् अरतिं देवम् ऋञ्जसे ॥
dyutānaṃ vo atithiṃ svarṇaram agniṃ hotāram manuṣaḥ svadhvaram | vipraṃ na dyukṣavacasaṃ suvṛktibhir havyavāham aratiṃ devam ṛñjase ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Him, your refulgent guest, Agni who comes from heaven, the Herald of mankind, well-skilled in sacred rites, Who, like a holy singer, utters heavenly words, oblation-bearer, envoy, God, I seek with hymns.
Translated by Ralph T. H. Griffith (1896)
