tánūnapāt pathá r̥tásya yā́nān mádhvā samañjánt svadayā sujihva |
mánmāni dhībhír utá yajñám r̥ndhán devatrā́ ca kr̥ṇuhy adhvarám naḥ ||2||

O Tanūnapāt (son of thyself?), do thou, anointing with honey (mádhu) the roads that go to righteousness (ṛtá), sweeten them, O well-tongued one; prospering (ṛdh) with prayers (did) the devotions (mánman) and the sacrifice, put (kṛ) thou also among the gods our service (adhvará).
