Unless we understand the original context in which Mark placed today’s gospel pericope, we won’t appreciate the important theological message he tried to convey.
Mark has just concluded his last prediction-misunderstanding-clarification passage on dying with Jesus. He and his disciples are leaving Jericho, the last town before they reach Jerusalem. The next narrative describes his triumphant Palm Sunday entrance into the holy city. Mark has just one bit of unfinished business before he narrates Jesus’ last days. His chance meeting with Bartimaeus will take care of that business.
