yád yodháyā maható mányamānān sā́kṣāma tā́n bāhúbhiḥ śā́śadānān |
yád vā nŕ̥bhir vŕ̥ta indrābhiyúdhyās táṃ tváyājíṃ sauśravasáṃ jayema ||4||

When thou hast urged the arrogant to combat, proud in their strength of arm, we will subdue them.
Or, Indra, when thou fightest girt by heroes, we in the glorious fray with thee will conquer.
