The last known king of Judah was Zedekiah. He is said to have temporarily escaped the clutches of the invading Babylonians, In 586 BCE, the invaders captured Jerusalem, they massacred much of the population, ransacked the holy temple - leaving it in ruins. They are also said to have taken many temple artefacts home with them. What happened to king Zedekiah? There is a cave named after him in Jerusalem where he was rumoured to have made his escape from the surrounding hoards.
There are further claims that the cave led the king and his troops several miles to the east, close to the Dead Sea. Alas, the king was reputedly captured there, by the Plains of Jericho. His eyes were gauged out after seeing is only sons slaughtered before him.
There remains just two pertinent questions. What then remained of the seed of Judah, which could be traced back to king David, an ancestor of Zedekiah? The awaited Messiah is supposed to be an heir of this royal line. Another perplexing mystery surrounds the fate of the fabled Ark of the Covenant. Legend has it that Jeremiah the Prophet, a contemporary of king Zedekiah, might have smuggled the cherished Ark, or other temple artefacts along the same route as the king's escape.
Therefore Zedekiah's Cave might be the portal for much more than an amazing undiscovered tunnel, with unknown depths, between the Old City of Jerusalem and the Dead Sea, the lowest point on earth.
