Bede the Venerable — as excerpted in the Catena Aurea on Luke 12:32-34

“Whether then should it be simply understood, that money kept faileth, but given away to our neighbour bears everlasting fruit in heaven; or, that the treasure of good works, if it be stored up for the sake of earthly advantage, is soon corrupted and perishes; but if it be laid up solely from heavenly motives, neither outwardly by the favour of men, as by the thief which steals from without, nor inwardly by vainglory, as by the moth which devours within, can it be defiled.”
