Śatapatha Brāhmaṇa ("of a hundred paths") 2.6.1.7

2.6.1.7

tadye somenejānāḥ | te pitaraḥ somavanto 'tha ye dattena pakvena lokaṃ jayanti te pitaro barhiṣado 'tha ye tato nānyataraccana yānagnireva dahantsvadayati te pitaro 'gniṣvāttā eta u ye pitaraḥ

Now those (fathers) who have sacrificed with Soma are the Pitarah Somavantah; and those who gain the world (of the gods) by means of cooked (sacrificial food) offered by them are the Pitaro Barhishadah; and they who (have offered) neither the one nor the other, and whom Agni consumes by burning, they are the Pitaro ’gnishvâttâh. These, then, are the fathers.
