RV 7.49.4
यासु राजा वरुणो यासु सोमो विश्वे देवा यासूर्जम् मदन्ति । वैश्वानरो यास्व् अग्निः प्रविष्टस् ता आपो देवीर् इह माम् अवन्तु ॥
yāsu rājā varuṇo yāsu somo viśve devā yāsūrjam madanti | vaiśvānaro yāsv agniḥ praviṣṭas tā āpo devīr iha mām avantu ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
They from whom Varuna the King, and Soma, and all the Deities drink strength and vigour, They into whom Vaisvanara Agni entered, here let those Waters, Goddesses, protect Me.
Translated by Ralph T. H. Griffith (1896)
