RV 1.44.12
यद् देवानाम् मित्रमहः पुरोहितो ऽन्तरो यासि दूत्यम् । सिन्धोर् इव प्रस्वनितास ऊर्मयो ऽग्नेर् भ्राजन्ते अर्चयः ॥
yad devānām mitramahaḥ purohito 'ntaro yāsi dūtyam | sindhor iva prasvanitāsa ūrmayo 'gner bhrājante arcayaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When as the Gods' High Priest, by many loved, thou dost their mission as their nearest Friend, Then, like the far-resounding billows of the flood, thy flames, O Agni, roar aloud.
Translated by Ralph T. H. Griffith (1896)
