Śatapatha Brāhmaṇa ("of a hundred paths") 1.7.3.8

1.7.3.8

tadvā agnaya iti kriyate | agnirvai sa devastasyaitāni nāmāni śarva iti yathā prācyā ācakṣate bhava iti yathā bāhīkāḥ paśūnām patī rudro 'gniriti tānyasyāśāntānyevetarāṇi nāmānyagnirityeva śāntatamaṃ tasmādagnaya iti kriyate sviṣṭakṛta iti

That (offering) then is certainly made to 'Agni,' for, indeed, Agni is that god;--his are these names: Sarva, as the eastern people call him; Bhava, as the Bâhîkas (call him); Pasûnâm pati ('lord of beasts,' Pasupati), Rudra, Agni. The name Agni, doubtless, is the most auspicious (sânta), and the other names of his are inauspicious: hence it is offered to (him under the name of) 'Agni,' and to (him as) the Svishtakrit.
