The Well of Bethesda was a magical place. I imagine that a whole lot of people live there and they all had a range of illnesses, ailments, infirmities etc. that they wanted to be healed from. The story goes that an angel would agitate the waters of the well and the first person to enter into the waters would be healed. This place probably became like a homeless shelter with a lot of old and elderly people living there hoping for the miracle of being healed. In the story there was a man who was so weak and feeble that he needed help to be able to enter the waters and by that time it would always be too late. In this story, Christ makes his way among them and over to that man and heals him.
