RV 6.3.1
अग्ने स क्षेषद् ऋतपा ऋतेजा उरु ज्योतिर् नशते देवयुष् टे । यं त्वम् मित्रेण वरुणः सजोषा देव पासि त्यजसा मर्तम् अंहः ॥
agne sa kṣeṣad ṛtapā ṛtejā uru jyotir naśate devayuṣ ṭe | yaṃ tvam mitreṇa varuṇaḥ sajoṣā deva pāsi tyajasā martam aṃhaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
True, guardian of the Law, thy faithful servant wins ample light and dwells in peace, O Agni, Whom thou, as Varuna in accord with Mitra, guardest, O God, by banishing his trouble.
Translated by Ralph T. H. Griffith (1896)
