RV 6.21.7
अभि त्वा पाजो रक्षसो वि तस्थे महि जज्ञानम् अभि तत् सु तिष्ठ । तव प्रत्नेन युज्येन सख्या वज्रेण धृष्णो अप ता नुदस्व ॥
abhi tvā pājo rakṣaso vi tasthe mahi jajñānam abhi tat su tiṣṭha | tava pratnena yujyena sakhyā vajreṇa dhṛṣṇo apa tā nudasva ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The demon's strength is gathered fast against thee: great as that strength hath grown, go forth to meet it. With thine own ancient friend and companion, the thunderbolt, brave Champion! drive it backward.
Translated by Ralph T. H. Griffith (1896)
