What the Bible says about Crystal Ball
(From Forerunner Commentary)
It is not likely that Ebed-Melech sways the king by humanitarian or moral considerations. He simply stresses to the king his belief that Jeremiah is a prophet about to die. Zedekiah probably acts to return Jeremiah to the relatively posh digs of the royal guards because he too realizes that Jeremiah is a prophet. He does not want to lose his crystal ball. Evidently, the king holds an audience with Jeremiah just after his release from the pit (verse 14).
