स त्वम् अग्ने सौभगत्वस्य विद्वान् अस्माकम् आयुः प्र तिरेह देव । तन् नो मित्रो वरुणो मामहन्ताम् अदितिः सिन्धुः पृथिवी उत द्यौः ॥
sa tvam agne saubhagatvasya vidvān asmākam āyuḥ pra tireha deva | tan no mitro varuṇo māmahantām aditiḥ sindhuḥ pṛthivī uta dyauḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Such, Agni, thou who knowest all good fortune, God, lengthen here the days of our existence. This prayer of ours may Varuna grant, and Mitra, and Aditi and Sindhu, Earth and Heaven.
Translated by Ralph T. H. Griffith (1896)
