RV 2.20.7
स वृत्रहेन्द्रः कृष्णयोनीः पुरन्दरो दासीर् ऐरयद् वि । अजनयन् मनवे क्षाम् अपश् च सत्रा शंसं यजमानस्य तूतोत् ॥
sa vṛtrahendraḥ kṛṣṇayonīḥ purandaro dāsīr airayad vi | ajanayan manave kṣām apaś ca satrā śaṃsaṃ yajamānasya tūtot ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Indra the Vrtra-slayer, Fort-destroyer, scattered the Dasa hosts who dwelt in darkness. For men hath he created earth and waters, and ever helped the prayer of him who worships.
Translated by Ralph T. H. Griffith (1896)
