RV 1.56.4
देवी यदि तविषी त्वावृधोतय इन्द्रं सिषक्त्य् उषसं न सूर्यः । यो धृष्णुना शवसा बाधते तम इयर्ति रेणुम् बृहद् अर्हरिष्वणिः ॥
devī yadi taviṣī tvāvṛdhotaya indraṃ siṣakty uṣasaṃ na sūryaḥ | yo dhṛṣṇunā śavasā bādhate tama iyarti reṇum bṛhad arhariṣvaṇiḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When Strength the Goddess, made more strong for help by thee, waits upon Indra as the Sun attends the Dawn, Then. he who with his might unflinching kills the gloom stirs up the dust aloft, with joy and triumphing.
Translated by Ralph T. H. Griffith (1896)
