RV 2.30.4
बृहस्पते तपुषाश्नेव विध्य वृकद्वरसो असुरस्य वीरान् । यथा जघन्थ धृषता पुरा चिद् एवा जहि शत्रुम् अस्माकम् इन्द्र ॥
bṛhaspate tapuṣāśneva vidhya vṛkadvaraso asurasya vīrān | yathā jaghantha dhṛṣatā purā cid evā jahi śatrum asmākam indra ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
As with a bolt, Brhaspati, fiercely flaming, pierce thou Vrkadvaras', the Asura's, heroes. Even as in time of old with might thou slewest, so slay even now our enemy, O Indra.
Translated by Ralph T. H. Griffith (1896)
