RV 3.28.5
अग्ने तृतीये सवने हि कानिषः पुरोळाशं सहसः सूनव् आहुतम् । अथा देवेष्व् अध्वरं विपन्यया धा रत्नवन्तम् अमृतेषु जागृविम् ॥
agne tṛtīye savane hi kāniṣaḥ puroḷāśaṃ sahasaḥ sūnav āhutam | athā deveṣv adhvaraṃ vipanyayā dhā ratnavantam amṛteṣu jāgṛvim ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
O Agni, at the third libation take with joy the offered cake of sacrifice, thou, Son of Strength. Through skill in song bear to the Gods our sacrifice, watchful and fraught with riches, to Immortal God.
Translated by Ralph T. H. Griffith (1896)
