'Fish gate' in the Bible

And the fish-gate did the sons of Senaah build: they laid its beams, and set up its doors, its locks and its bars.

and from above the gate of Ephraim, and above the gate of the old wall, and above the fish-gate, and the tower of Hananeel, and the tower of Meah, even to the sheep-gate; and they stood still in the prison-gate.
