RV 10.87.20
त्वं नो अग्ने अधराद् उदक्तात् त्वम् पश्चाद् उत रक्षा पुरस्तात् । प्रति ते ते अजरासस् तपिष्ठा अघशंसं शोशुचतो दहन्तु ॥
tvaṃ no agne adharād udaktāt tvam paścād uta rakṣā purastāt | prati te te ajarāsas tapiṣṭhā aghaśaṃsaṃ śośucato dahantu ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Guard us, O Agni, from above and under, protect us from behind us and before us; And may thy flames, most fierce and never wasting, glowing with fervent heat, consume the sinner.
Translated by Ralph T. H. Griffith (1896)
