Lesson of the widow's mite
The lesson of the widow's mite or the widow's offering is presented in two of the Synoptic Gospels (Mark 12:41–44 and Luke 21:1–4), when Jesus is teaching in the Temple in Jerusalem. The Gospel of Mark specifies that two mites (Greek lepta) are together worth a quadrans, the smallest Roman coin.
