5.3.8

uruvyácā no mahiṣáḥ śárma yachatv asmín háve puruhūtáḥ purukṣú |
sá naḥ prajā́yai haryaśva mr̥ḍéndra mā́ no rīriṣo mā́ párā dāḥ ||8||

Let the bull (mahiṣá) of wide expanse grant us protection, having much food (-kṣú), [he] the much-invoked in this invocation; do thou be gracious unto our progeny, O thou of the bay horses; O Indra, harm us not, do not abandon us.
