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.
Or, the thieves are heretics and evil spirits, who are bent upon depriving us of spiritual things. The moth which secretly frets the garments is envy, which mars good desires, and bursts the bonds of charity.
