Śatapatha Brāhmaṇa ("of a hundred paths") 5.3.5.12

5.3.5.12

audumbaram bhavati | tena svo 'bhiṣiñcatyannaṃ vā ūrgudumbara ūrgvai svaṃ yāvadvai puruṣasya svam bhavati naiva tāvadaśanāyati tenorkṣvaṃ tasmādaudumbareṇa svo 'bhiṣiñcati

There is an udumbara (ficus glomerata) one: therewith one of his own (kinsmen, or brothers) sprinkles. The udumbara tree means sustenance, (that is) food, and the 'own' means sustenance, for as far as a man's own goes, so far he does not hunger: thereby his 'own' is sustenance, and therefore one of his own (kinsmen) sprinkles with an udumbara (vessel).
