RV 4.13.4
वहिष्ठेभिर् विहरन् यासि तन्तुम् अवव्ययन्न् असितं देव वस्म । दविध्वतो रश्मयः सूर्यस्य चर्मेवावाधुस् तमो अप्स्व् अन्तः ॥
vahiṣṭhebhir viharan yāsi tantum avavyayann asitaṃ deva vasma | davidhvato raśmayaḥ sūryasya carmevāvādhus tamo apsv antaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Spreading thy web with mightiest Steeds thou comest, rending apart, thou God, the black-hued mantle. The rays of Surya tremulously shining sink, like a hide, the darkness in the waters.
Translated by Ralph T. H. Griffith (1896)
