Dungeon

Dungeon designates a place of confinement more severe than an ordinary prison, characterized by darkness, restricted space, and extreme hardship. In the patriarchal narratives, Joseph was cast into an empty cistern (literally "the pit") by his brothers and later confined in Pharaoh's prison (Gen. 39:20; 40:3; 41:10; 42:19). Jeremiah was lowered by ropes into a muddy cistern-dungeon where he sank in the mire, rescued only through the intercession of the Ethiopian court official Ebed-melech (Jer. 38:6–13)—one of Scripture's most vivid accounts of political imprisonment.

The "inner prison" of Acts 16:24, where Paul and Silas were placed with their feet in stocks after flogging at Philippi, corresponds to the most secure section of the Roman prison—reserved for the most dangerous or condemned prisoners. The Psalms use dungeon imagery to describe extreme spiritual distress (Ps. 88:8; 142:7), and Isaiah 42:7 and 61:1 include release of prisoners from dungeons among the promises of the coming servant and the Spirit-anointed herald. These texts shaped Jesus's own programmatic announcement in Luke 4:18.
