What does Luke 21:2 mean?

Jesus and His disciples are on the temple Mount, shortly before the crucifixion. It is Passover, and the city is overflowing with people. Jews were only required to come to Jerusalem three times a year: for Passover, Pentecost, and the Feast of Booths. Many used these visits to perform required sacrifices and give offerings.

Jesus notices rich people donating large amounts of money to the temple. The money may be used for repairs, enhancements, or to support the priests and Levites. Then, Jesus notices a destitute widow offer two copper coins, or lepta. In total, her offering is worth about 1/50th of a laborer's daily wage.

We're not told why this woman is destitute. It was difficult for unmarried, childless women to support themselves and own land in that era. It may be that some of the scribes walking around in long robes took advantage of her situation and took money from her (Luke 20:46–47). That is not God's heart. In fact, the Mosaic law states that His wrath burns against those who abuse widows (Exodus 22:22–24).

Neither do we know why the widow donated her last two coins. Perhaps she considered buying a little bit of grain but realized a small meal was nothing compared to her great God. That faith and love for God is why we celebrate her story two millennia later.
