There were only 2 miracles performed by Jesus that were recorded as happening in Jerusalem. One of them has to do with a blind man who was commanded by Jesus to go and wash in the Pool of Siloam (after Jesus spit and rubbed dirt in the blind man’s eyes).
We visited the Pool of Siloam. There is a huge tunnel that runs from Jerusalem down to the pool. You can actually walk through the tunnel. It takes approximately 30 minutes to get to the top. Our group did not make the jaunt (we are actually quite tired…) but I would have loved to do it. Maybe next time (haha).
