Bede the Venerable
Catena Aurea · Lukasevangelium 12
Fear not, little flock; for it is your Father’s good pleasure to give you the kingdom. Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth. For where your treasure is, there will your heart be also.
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.
