RV 10.88.9
यं देवासो ऽजनयन्ताग्निं यस्मिन्न् आजुहवुर् भुवनानि विश्वा । सो अर्चिषा पृथिवीं द्याम् उतेमाम् ऋजूयमानो अतपन् महित्वा ॥
yaṃ devāso 'janayantāgniṃ yasminn ājuhavur bhuvanāni viśvā | so arciṣā pṛthivīṃ dyām utemām ṛjūyamāno atapan mahitvā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He, Agni, whom the Gods have generated, in whom they offered up all worlds and creatures, He with his bright glow heated earth and heaven, urging himself right onward in his grandeur.
Translated by Ralph T. H. Griffith (1896)
