Śatapatha Brāhmaṇa ("of a hundred paths") 2.4.3.6

2.4.3.6

kṣatraṃ vā indrāgnī | viśo viśve devā yatra vai kṣatramujjayatyanvābhaktā vai tatra viṭtadviśvāndevānanvābhajatāṃ tasmādeṣa vaiśvadevaścarurbhavati

Now, Indra and Agni are the Kshatra (nobility), and all the gods (or, the All-gods) are the Vis (common Âryan people); and wherever the Kshatra conquers, there the Vis is allowed to share. Thus they (Indra and Agni) allowed the Visve Devâh (the All-gods) a share (in the offering); and hence that pap of boiled (rice or barley) grain (offered) to the All-gods.
