RV 1.161.3
अग्निं दूतम् प्रति यद् अब्रवीतनाश्वः कर्त्वो रथ उतेह कर्त्वः । धेनुः कर्त्वा युवशा कर्त्वा द्वा तानि भ्रातर् अनु वः कृत्व्य् एमसि ॥
agniṃ dūtam prati yad abravītanāśvaḥ kartvo ratha uteha kartvaḥ | dhenuḥ kartvā yuvaśā kartvā dvā tāni bhrātar anu vaḥ kṛtvy emasi ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
What to the envoy Agni in reply ye spake, A courser must be made, a chariot fashioned here, A cow must be created, and the Twain made young. When we have done these things, Brother, we turn to you.
Translated by Ralph T. H. Griffith (1896)
