'Prison house' in the Bible

But the Philistines took him, and put out his eyes; and brought him down to Gaza, and bound him with fetters. And he was made to grind in the prison house.

And when their hearts were merry, they said, "Send for Samson and let him play before us." And they fetched Samson out of the prison house, and he played before them, and they set him between the pillars.
