A certain poor widow cast in two mites, which make a farthing. Not as if one mite made a farthing, as Euthymius understands, relying on Matthew 5:26. But two mites were equivalent to one farthing, as is here clearly expressed. For a farthing was the fourth part of a little ass; and ten small asses made a denarius. A mite was half a farthing.
The poor widow cast only two pennies into the treasury; yet because she gave all she had it is said of her that she surpassed all the rich in offering gifts to God. Such gifts are valued not by their weight but by the good will with which they are made. Letter , To Julian
I pass on to the widow in the Gospel who though she was but a poor widow was yet richer than all the people of Israel.

But since it was not money but rather her intention that prevailed, that woman received everything because she demonstrated firm conviction. Therefore, let us not say that the kingdom may be bought with money. It is not bought with money, but rather with an unsullied intention that may demonstrate itself by means of money. Therefore, one answers, is there no need for money? There is no need for money, but for a Christian disposition. If you have this, you will even be able to buy heaven with two small copper coins. Without this disposition, one will not be able to do with ten thousand talents of gold the very thing that the two coins can do. Why? Because whenever you have many things and deposit a lesser amount, you have given alms, but not the same kind of alms that the widow gave. For you were ...
And Christ our Lord and Master, and Searcher of hearts, saw her, and said, Verily I say unto you, that this widow hath cast into the treasury more than they all: for all they have cast in of their abundance, but this woman of her penury hath cast in all the living that she had."
