'Dungeon' in the Bible

When Jeremiah had come into the vaulted cell in the dungeon and had remained there many days,

So they took Jeremiah and threw him into the cistern of Malchijah the king’s son, which was in the court of the guardhouse; and they let Jeremiah down [into the cistern] with ropes. Now there was no water in the cistern but only mud, and Jeremiah sank in the mud.

Now Ebed-melech the Ethiopian (Cushite), one of the eunuchs who was in the king’s palace, heard that they had put Jeremiah in the cistern, and while the king was sitting in the Gate of Benjamin,

“My lord the king, these men have acted wickedly in all that they have done to Jeremiah the prophet whom they have thrown into the cistern; and he will die [of hunger] where he is because of the famine, for there is no more bread in the city.”

Then the king commanded Ebed-melech the Ethiopian, saying, “Take thirty men from here with you and lift Jeremiah the prophet out of the cistern before he dies.”

So Ebed-melech took the men with him and went into the palace of the king to a place under the storeroom and took from there old rags and worn-out clothes and let them down by ropes into the cistern to Jeremiah.

So they pulled Jeremiah up with the ropes and took him up out of the cistern; and Jeremiah remained in the court of the guardhouse.
