RV 3.30.15
इन्द्र दृह्य यामकोशा अभूवन् यज्ञाय शिक्ष गृणते सखिभ्यः । दुर्मायवो दुरेवा मर्त्यासो निषङ्गिणो रिपवो हन्त्वासः ॥
indra dṛhya yāmakośā abhūvan yajñāya śikṣa gṛṇate sakhibhyaḥ | durmāyavo durevā martyāso niṣaṅgiṇo ripavo hantvāsaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Barring the way they come. Be firm, O Indra; aid friends to sacrifice and him who singeth. These must be slain by thee, malignant mortals, armed with ill arts, our quiver bearing foemen.
Translated by Ralph T. H. Griffith (1896)
