'Prison house' in the Bible

And the Philistines took him and put out his eyes, and brought him down to Gaza, and bound him with fetters of brass. And he ground in the prison house.

And when their hearts were merry, it happened that they said, Call for Samson and he will make sport for us. And they called for Samson out of the prison house. And he made sport for them, and they set him between the pillars.
