Pseudo-Jerome
Catena Aurea · Markusevangelium 12
And Jesus sat over against the treasury, and beheld how the people cast money into the treasury: and many that were rich cast in much. And there came a certain poor widow, and she threw in two mites, which make a farthing. And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury: For all they did cast in of their abundance; but she of her want did cast in all that she had, even all her living.
But in a mystical sense, they are rich, who bring forth from the treasure of their heart things new and old, which are the obscure and hidden things of Divine wisdom in both testaments; but who is the poor woman, if it be not I and those like me, who cast in what I can, and have the will to explain to you, where I have not the power. For God does not consider how much ye hear, but what is the store from which it comes; but each at all events can bring his farthing, that is, a ready will, which is called a farthing, because it is accompanied by three things, that is, thought, word, and deed. And in that it is said that she cast in all her living, it is implied that all that the body wants is that by which it lives1; wherefore it is said, All the labour of man is for his mouth. (Eccl. 6:7)
