In the first reading today regarding Elijah and the widow, I think this offers biblical precedent for “Woman make me a sammich.”
As for the second part of the Gospel today I recently read that according to the Talmud, there were thirteen trumpet-shaped receptacles for offerings for the temple. The horns were called a shofar which acted as a funnel into a chest. Each one of these Shofar-chests had an inscription.
So what Jesus is saying is that those who placed money in the treasury as an act of their own aggrandizement ultimately had nothing to shofar it.
