RV 8.39.8
यो अग्निः सप्तमानुषः श्रितो विश्वेषु सिन्धुषु । तम् आगन्म त्रिपस्त्यम् मन्धातुर् दस्युहन्तमम् अग्निं यज्ञेषु पूर्व्यं नभन्ताम् अन्यके समे ॥
yo agniḥ saptamānuṣaḥ śrito viśveṣu sindhuṣu | tam āganma tripastyam mandhātur dasyuhantamam agniṃ yajñeṣu pūrvyaṃ nabhantām anyake same ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni who liveth in all streams, Lord of the Sevenfold Race of men, Him dweller in three homes we seek, best slayer of the Dasytis for Mandhatar, first in sacrifice. Let all the others die away.
Translated by Ralph T. H. Griffith (1896)
