10.9.3

bā́lās te prókṣaṇīḥ santu jīhvā́ sáṃ mārṣṭu aghnye |
śuddhā́ tváṃ yajñíyā bhūtvā́ dívaṃ préhi śataudane ||3||

Be thy tail-tuft the sprinklers; let thy tongue do the cleansing, O inviolable one; do thou, having become clean, fit for sacrifice, go on to heaven, O thou of the hundred rice-dishes.
