RV 4.2.16
अधा यथा नः पितरः परासः प्रत्नासो अग्न ऋतम् आशुषाणाः । शुचीद् अयन् दीधितिम् उक्थशासः क्षामा भिन्दन्तो अरुणीर् अप व्रन् ॥
adhā yathā naḥ pitaraḥ parāsaḥ pratnāso agna ṛtam āśuṣāṇāḥ | śucīd ayan dīdhitim ukthaśāsaḥ kṣāmā bhindanto aruṇīr apa vran ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
As in the days of old our ancient Fathers, speeding the work of holy worship, Agni, Sought pure light and devotion, singing praises; they cleft the ground and made red Dawns apparent.
Translated by Ralph T. H. Griffith (1896)
