RV 7.19.5
तव च्यौत्नानि वज्रहस्त तानि नव यत् पुरो नवतिं च सद्यः । निवेशने शततमाविवेषीर् अहञ् च वृत्रं नमुचिम् उताहन् ॥
tava cyautnāni vajrahasta tāni nava yat puro navatiṃ ca sadyaḥ | niveśane śatatamāviveṣīr ahañ ca vṛtraṃ namucim utāhan ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
These were thy mighty powers that, Thunder-wielder, thou swiftly crushedst nine-and-ninety castles: Thou capturedst the hundredth in thine onslaught; thou slewest Namuci, thou slewest Vrtra.
Translated by Ralph T. H. Griffith (1896)
