'Fish gate' in the Bible

and the fish-gate have sons of Hassenaah built, they have walled it, and set up its doors, its locks, and its bars.

and from beyond the gate of Ephraim, and by the old-gate, and by the fish-gate, and the tower of Hananeel, and the tower of Meah, and unto the sheep-gate -- and they have stood at the prison-gate.
