Śatapatha Brāhmaṇa ("of a hundred paths") 1.8.2.15

1.8.2.15

vasuvane vasudheyasyeti | devatāyā eva vaṣaṭkriyate devatāyai hūyate na vā atra devatāstyanuyājeṣu devam barhiriti tatra nāgnirnendro na somo devo narāśaṃsa iti ṛta ekaṃ cana yo vā atrāgnirgāyatrī sa nidānena

['The divine Barhis (or Narâsamsa) may accept (the offering)] for abundant obtainment of abundant gift! [Vaushat!]' For a deity only the vashat-call is pronounced, to a deity only offering is made; but here at the after-offerings there is no (proper) deity. When he says 'The divine Barhis,' in this there is neither Agni, nor Indra, nor Soma; when he says 'The divine Narâsamsa,' neither is there in this anything whatever (of the nature of a god); and what Agni there is (in the third offering-prayer), he indeed is virtually the gâyatrî.
