RV 4.1.7
त्रिर् अस्य ता परमा सन्ति सत्या स्पार्हा देवस्य जनिमान्य् अग्नेः । अनन्ते अन्तः परिवीत आगाच् छुचिः शुक्रो अर्यो रोरुचानः ॥
trir asya tā paramā santi satyā spārhā devasya janimāny agneḥ | anante antaḥ parivīta āgāc chuciḥ śukro aryo rorucānaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Three are those births, the true, the most exalted, eagerly longed-for, of the God, of Agni. He came invested in the boundless region, pure, radiant, friendly, mightily resplendent.
Translated by Ralph T. H. Griffith (1896)
