20.34.4

yénemā́ víśvā cyávanā kr̥tā́ni yó dā́saṃ várṇam ádharaṃ gúhā́kaḥ |
śvaghnī́va yó jigīvā́ṃ lakṣám ā́dad aryáḥ puṣṭā́ni sá janāsa índraḥ ||4||

By whom this universe was made to tremble, who chased away the humbled brood of demon, Who, like a gambler gathering his winnings, seized the foe's riches, He, O men, is Indra.
