This was in the Babylonian siege of Jerusalem, when Zedekiah, king of Judah, fled to Jericho. Today we know that the gate between the walls, from which Zedekiah fled, is located in the south of the city, but the name "Zedekiah's Cave" stuck to the cave. The water spills that appear at the end of the cave are still referred to as Zedekiah's tears.
There is also a Muslim tradition linking the cave to the place where Korach and his congregation were swallowed up in the ground, as punishment for Korach's attempt to rebel against Moses.
But let's go back to our story. In 1854, Dr. Berkeley and his son took their dog for a walk. At one point the dog disappeared and all attempts to find him failed. When the father and son had given up on finding the dog, they suddenly discovered a deep hole. From there they heard the bark of a dog. After the two managed to rescue the poor dog from the depths of the earth, they returned to their homes. But that evening Dr. Berkeley decided to return to the mysterious pit and brought some of his aides. He went down into the depths of the hole and discovered a huge cave in front of him. It was an amazing cave the size and beauty of which Berkeley had studied all night.
This is how the Zedekiah Cave, the largest cave in Jerusalem and in Israel, was discovered. It is considered one of the most spectacular sites in the city and is open to the general public.
