In today’s Gospel we discover that Jesus had sharp hearing but to understand how we know this we must understand where he was standing.  

Jesus is in the temple area. It was a series of courtyards. The first and largest was the courtyard of the gentiles. This did not mean that only gentiles could use it but that everyone including gentiles could. The next was the court of the women which again was not just for women but for all Jews. The spaces narrowed further with a court for just Jewish men, then priests and finally the Holy of Holys which only the High Preist could enter once a year at Yom Kippur. The temple was huge and tremendously expensive to maintain. One revenue source was donations from visitors. The temple authorities were very shrewd. First, as they used coins, they made the collection boxes from metal. More and larger coins made more noise and caused more attention to be paid to the donor. They were in fact called the trumpets. Also, there were twelve of them, each one for a different purpose, from care of the gold of the temple to doweries for the daughters of poor priestly families. A person could donate to several of them, and everyone would hear their generosity.  Truly getting a bang for their buck. And most importantly they were placed in the court of the women so women could donate as well. 

This is where Jesus has placed himself. He sees the rich come forward and hears the conspicuous noise they made putting their large coins perhaps in several trumpets. They were aware of who they were and expected everyone to notice and admire.
