8.3.18

sanā́d agne mr̥ṇasi yātudhā́nān ná tvā rákṣāṃsi pŕ̥tanāsu jigyuḥ |
sahámūrān ánu daha kravyā́do mā́ te hetyā́ mukṣata dáivyāyāḥ ||18||

From of old, O Agni, thou killest the sorcerers; the demons have not conquered thee in fights; burn up the flesh-eaters together with their dupes (? mūrá); let them not be freed from thy heavenly missile.
