RV 10.50.5
अवा नु कं ज्यायान् यज्ञवनसो महीं त ओमात्रां कृष्टयो विदुः । असो नु कम् अजरो वर्धाश् च विश्वेद् एता सवना तूतुमा कृषे ॥
avā nu kaṃ jyāyān yajñavanaso mahīṃ ta omātrāṃ kṛṣṭayo viduḥ | aso nu kam ajaro vardhāś ca viśved etā savanā tūtumā kṛṣe ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Help now, as Highest, those who toil at sacrifice: well do the people know thy great protecting might. Thou shalt be everlasting, Giver of success yea, on all these libations thou bestowest strength.
Translated by Ralph T. H. Griffith (1896)
