RV 3.15.3
त्वं नृचक्षा वृषभानु पूर्वीः कृष्णास्व् अग्ने अरुषो वि भाहि । वसो नेषि च पर्षि चात्य् अंहः कृधी नो राय उशिजो यविष्ठ ॥
tvaṃ nṛcakṣā vṛṣabhānu pūrvīḥ kṛṣṇāsv agne aruṣo vi bhāhi | vaso neṣi ca parṣi cāty aṃhaḥ kṛdhī no rāya uśijo yaviṣṭha ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Bull, who beholdest men, through many mornings, among the dark ones shine forth red, O Agni. Lead us, good Lord, and bear us over trouble: Help us who long, Most Youthful God, to riches.
Translated by Ralph T. H. Griffith (1896)
