RV 5.11.6
त्वाम् अग्ने अङ्गिरसो गुहा हितम् अन्व् अविन्दञ् छिश्रियाणं वने-वने । स जायसे मथ्यमानः सहो महत् त्वाम् आहुः सहसस् पुत्रम् अङ्गिरः ॥
tvām agne aṅgiraso guhā hitam anv avindañ chiśriyāṇaṃ vane-vane | sa jāyase mathyamānaḥ saho mahat tvām āhuḥ sahasas putram aṅgiraḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
O Agni, the Angirases discovered thee what time thou layest hidden, fleeing back from wood to wood. Thou by attrition art produced as conquering might, and men, O Angiras, call thee the Son of Strength.
Translated by Ralph T. H. Griffith (1896)
