The Pool of Siloam, also called the Pool of Shiloah (Isaiah 8:6), has a rich and storied history, which involves an ancient king of Judah, a famous sermon, and one of Christ’s great miracles. The word Siloam means “Sent” (John 9:7). Several rabbinic traditions identified the Pool of Siloam as the Messiah’s Pool. It was the only source of fresh water within the walls of ancient Jerusalem.
