Śatapatha Brāhmaṇa ("of a hundred paths") 10.2.3.7

10.2.3.7

te ye ha tathā kurvanti etaṃ ha te pitaram prajāpatiṃ sampadaścyāvayanti ta iṣṭvā pāpīyāṃso bhavanti pitaraṃ hi prajāpatiṃ sampadaścyāvayanti sā yāvatyeṣā saptavidhasya vedistāvatīṃ caturdaśa kṛtva ekaśatavidhasya vediṃ vimimīte

As large as this Vedi of the sevenfold (fire-altar) is, fourteen times as large he measures out the Vedi of the one hundred and one-fold (altar).
