RV 10.138.5
अयुद्धसेनो विभ्वा विभिन्दता दाशद् वृत्रहा तुज्यानि तेजते । इन्द्रस्य वज्राद् अबिभेद् अभिश्नथः प्राक्रामच् छुन्ध्यूर् अजहाद् उषा अनः ॥
ayuddhaseno vibhvā vibhindatā dāśad vṛtrahā tujyāni tejate | indrasya vajrād abibhed abhiśnathaḥ prākrāmac chundhyūr ajahād uṣā anaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Armed with resistless weapons, with vast power to cleave, the Vrtra-slayer whets his darts and deals fordi wounds. Bright Usas was afraid of Indra's slaughtering bolt: she went upon her way and left her chariot there.
Translated by Ralph T. H. Griffith (1896)
