The story from the Bible the artist is depicting is the road to Emmaus from Luke 24:13-30. The story is about two men walking along a path and talking about what happened before Jesus had risen from the dead. Jesus heard them and decided to engage in the conversation even though He was the topic of the conversation. They told Him what had been going on. As they walked, Jesus taught them the truth of His death and resurrection. They didn't notice that it was Jesus until they were having supper.
