Atharvaveda Samhita — Kanda 7 — Chapter 62
AV 7 62.1
अयम् अग्निः सत्पतिर् वृद्धवृष्णो रथीव पत्तीन् अजयत् पुरोहितः । नाभा पृथिव्यां निहितो दविद्युतद् अधस्पदं कृणुतां ये पृतन्यवः
ayam agniḥ satpatir vṛddhavṛṣṇo rathīva pattīn ajayat purohitaḥ | nābhā pṛthivyāṃ nihito davidyutad adhaspadaṃ kṛṇutāṃ ye pṛtanyavaḥ
This Agni, lord of the good, of grown manly strength, has conquered like a chariot-fighter (conquering) foot-soldiers, (he) set in front (as purohita); placed in the navel on the earth, flashing brightly — let him put underfoot those who attack us.

Compare with Ralph T.H. Griffith
Like a car-warrior, Agni here, grown mighty, Lord of the brave, Chief Priest, hath conquered footmen. Laid on earth's centre he hath flashed and glittered. Low may he lay our enemies beneath us.
— tr. Ralph T.H. Griffith (1895–96)
