Luke 21:1

In the Greek language, φυλάξαι signifies to keep, and gaza in Persian means riches, hence gazophylacium is used for the name of the place in which money is kept. Now there was a chest with an opening at the top placed near the altar, on the right hand of those entering the house of God, into which the Priests cast all the money, which was given for the Lord's temple. But our Lord as He overthrows those who trade in His house, so also He remarks those who bring gifts, giving praise to the deserving, but condemning the bad. Hence it follows, And he saw also a certain poor widow casting in thither two mites.

Now mystically, the rich men who cast their gifts into the treasury signify the Jews puffed up with the righteousness of the law; the poor widow, the simplicity of the Church which is called poor, because it has either cast away the spirit of pride, or its sins, as if they were worldly riches. But the Church is a widow, because her Husband endured death for her. She cast two mites into the treasury, because in God's sight, in whose keeping are all the offerings of our works, she presents her gifts, whether of love to God and her neighbour, or of faith and prayer. And these excel all the works of the proud Jews, for they of their abundance cast into the offerings of God, in that they presume on their righteousness, but the Church casts in all her living, for every thing that hath life she believes to be the gift of God.

Or the widow may be taken to mean any soul bereft as it were of her first husband, the ancient law, and not worthy to be united to the Word of God. Who brings to God instead of a dowry faith and a good conscience, and so seems to offer more than those who are rich in words, and abound in the moral virtues of the Gentiles.

(non occ.) Our Lord having rebuked the covetousness of the Scribes who devoured widows' houses, commends the almsgiving of a widow; as it is said, And he looked up, and saw the rich men casting into the treasury, & c.
