RV 5.30.7
वि षू मृधो जनुषा दानम् इन्वन्न् अहन् गवा मघवन् संचकानः । अत्रा दासस्य नमुचेः शिरो यद् अवर्तयो मनवे गातुम् इच्छन् ॥
vi ṣū mṛdho januṣā dānam invann ahan gavā maghavan saṃcakānaḥ | atrā dāsasya namuceḥ śiro yad avartayo manave gātum icchan ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Thou, Maghavan, from the first didst scatter foemen, speeding, while joying in the milk, the Giver. There, seeking man's prosperity, thou torest away the head of Namuci the Dasa.
Translated by Ralph T. H. Griffith (1896)
