This is the day that just won't end for our Hero. He is being hounded on every side in these last few days before days before the final Passover in Jerusalem. Jesus has shied away from no one. All questions have been answered so perfectly that everyone is giving up on trying to take Him out this way. But before the Pharisees pack it in and leave Jesus switches the roles and He asks them a question. Jesus began the setup for this question with His answer to the last question that He was asked. These men really think that they know all that there is to know about God. With this question they are about to find out how little they actually know.
