Śatapatha Brāhmaṇa ("of a hundred paths") 11.3.3.5

11.3.3.5

atha yadātmānaṃ daridrīkṛtyeva ahrīrbhūtvā bhikṣate ya evāsya mṛtyau pādastameva tena parikrīṇāti taṃ saṃskṛtyātmandhatte sa enamāviśati

And when, having made himself poor, as it were, and become devoid of shame, he begs alms, then he redeems that part of his which is in death; and, having cleansed it, he takes it to himself, and it enters him.
