RV 4.50.4
बृहस्पतिः प्रथमं जायमानो महो ज्योतिषः परमे व्योमन् । सप्तास्यस् तुविजातो रवेण वि सप्तरश्मिर् अधमत् तमांसि ॥
bṛhaspatiḥ prathamaṃ jāyamāno maho jyotiṣaḥ parame vyoman | saptāsyas tuvijāto raveṇa vi saptaraśmir adhamat tamāṃsi ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Brhaspati, when first he had his being from mighty splendour in supremest heaven, Strong, with his sevenfold mouth, with noise of thunder, with his seven rays, blew and dispersed the darkness.
Translated by Ralph T. H. Griffith (1896)
