[Jesus] looked up and saw rich people putting their gifts into the treasury; he also saw a poor widow put in two small copper coins. He said, "Truly I tell you, this poor widow has put in more than all of them; for all of them have contributed out of their abundance, but she out of her poverty has put in all she had to live on" (Lk 21:1-4, NRSV).

[J]ust as Jesus indicts the religious leadership for consuming the homes of widows, so now he laments the travesty of a religious system that has as its effect the devouring of this widow's livelihood. Note that in no way does Luke suggest that Jesus finds the widow's action exemplary or praiseworthy. How could he, when the religious system was supposed to care for such as these (cf. Acts 6:1-6), not render them utterly destitute? Jesus' mission is to bring good news to the poor, including this widow, not to impoverish the poor even further (Joel B. Green, "The Gospel of Luke", 728).
