RV 6.18.5
तन् नः प्रत्नं सख्यम् अस्तु युष्मे इत्था वदद्भिर् वलम् अङ्गिरोभिः । हन्न् अच्युतच्युद् दस्मेषयन्तम् ऋणोः पुरो वि दुरो अस्य विश्वाः ॥
tan naḥ pratnaṃ sakhyam astu yuṣme itthā vadadbhir valam aṅgirobhiḥ | hann acyutacyud dasmeṣayantam ṛṇoḥ puro vi duro asya viśvāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Be this our ancient bond of friendship with you and with Angirases here who speak of Vala. Thou, Wondrous, Shaker of things firm, didst smite him in his fresh strength, and force his doors and castles.
Translated by Ralph T. H. Griffith (1896)
