In the summer of 2004 Eli Shukrun, Ronny Reich, and John Seligman, who were checking the area southeast of the traditional “Pool of Siloam” for a public works project, discovered a pool that they date to the first centuries B.C. and A.D. In all probability it is the “Pool of Siloam” mentioned in John 9:7—to which Jesus sent a blind man to wash a mud mixture from his eyes.
This pool is also mentioned in Rabbinic sources in connection with the water rituals associated with the Feast of Tabernacles— in the fall of the year.
