RV 3.26.2
तं शुभ्रम् अग्निम् अवसे हवामहे वैश्वानरम् मातरिश्वानम् उक्थ्यम् । बृहस्पतिम् मनुषो देवतातये विप्रं श्रोतारम् अतिथिं रघुष्यदम् ॥
taṃ śubhram agnim avase havāmahe vaiśvānaram mātariśvānam ukthyam | bṛhaspatim manuṣo devatātaye vipraṃ śrotāram atithiṃ raghuṣyadam ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
That Agni, bright, Vaisvanara, we invoke for help, and Matarisvan worthy of the song of praise; Brhaspati for man's observance of the Gods, the Singer prompt to hear, the swiftly-moving guest.
Translated by Ralph T. H. Griffith (1896)
