Cyril of Alexandria — as excerpted in the Catena Aurea on Luke 21:1-4

“She offered two oboli, which with the sweat of her brow she had earned for her daily living, or what she daily begs for at the hands of others she gives to God, shewing that her poverty is fruitful to her. Therefore does she surpass the others, and by a just award receives a crown from God; as it follows, Of a truth I say unto you, that this poor widow hath cast in more, &c.”
