RV 10.88.8
सूक्तवाकम् प्रथमम् आद् इद् अग्निम् आद् इद् धविर् अजनयन्त देवाः । स एषां यज्ञो अभवत् तनूपास् तं द्यौर् वेद तम् पृथिवी तम् आपः ॥
sūktavākam prathamam ād id agnim ād id dhavir ajanayanta devāḥ | sa eṣāṃ yajño abhavat tanūpās taṃ dyaur veda tam pṛthivī tam āpaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
First the Gods brought the hymnal into being; then they engendered Agni, then oblation. He was their sacrifice that guards our bodies: him the heavens know, the earth, the waters know him.
Translated by Ralph T. H. Griffith (1896)
