'Cistern' in the Bible

So the officials took Jeremiah and put him in the cistern of Malkijah, one of the royal princes, that was in the courtyard of the guardhouse. There was no water in the cistern, only mud. So when they lowered Jeremiah into the cistern with ropes he sank in the mud.

An Ethiopian, Ebed Melech, a court official in the royal palace, heard that Jeremiah had been put in the cistern. While the king was holding court at the Benjamin Gate,

"Your royal Majesty, those men have been very wicked in all that they have done to the prophet Jeremiah. They have thrown him into a cistern and he is sure to die of starvation there because there is no food left in the city.

Then the king gave Ebed Melech the Ethiopian the following order: "Take thirty men with you from here and go pull the prophet Jeremiah out of the cistern before he dies."

So Ebed Melech took the men with him and went to a room under the treasure room in the palace. He got some worn-out clothes and old rags from there and let them down by ropes to Jeremiah in the cistern.

So they pulled Jeremiah up from the cistern with ropes. Jeremiah, however, still remained confined to the courtyard of the guardhouse.

But as soon as they were inside the city, Ishmael son of Nethaniah and the men who were with him slaughtered them and threw their bodies in a cistern.

Now the cistern where Ishmael threw all the dead bodies of those he had killed was a large one that King Asa had constructed as part of his defenses against King Baasha of Israel. Ishmael son of Nethaniah filled it with dead bodies.
