RV 3.15.4
अषाळ्हो अग्ने वृषभो दिदीहि पुरो विश्वाः सौभगा संजिगीवान् । यज्ञस्य नेता प्रथमस्य पायोर् जातवेदो बृहतः सुप्रणीते ॥
aṣāḷho agne vṛṣabho didīhi puro viśvāḥ saubhagā saṃjigīvān | yajñasya netā prathamasya pāyor jātavedo bṛhataḥ supraṇīte ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Shine forth, a Bull invincible, O Agni, winning by conquest all the forts and treasures, Thou Jatavedas who art skilled in guiding, the chief high saving sacrifice's Leader.
Translated by Ralph T. H. Griffith (1896)
