Bede the Venerable — as excerpted in the Catena Aurea on Luke 21:1-4

“For whatever we offer with an honest heart is well pleasing to God, who hath respect unto the heart, not the substance, nor does He weigh the amount of that which is given in sacrifice, but of that from which it is taken; as it follows, For all these have cast in of their abundance, but she all that she had.”
