'Fish gate' in the Bible

But the fish gate did the sons of Hassenaah build, who also laid the beams thereof, and set up the doors thereof, the locks thereof, and the bars thereof.

And from above the gate of Ephraim, and above the old gate, and above the fish gate, and the tower of Hananeel, and the tower of the hundred, even unto the sheep gate: and they stopped at the gate of the guard.
