'Fish gate' in the Bible

And the sons of Hassenaah built the fish gate. They laid the beams of it, and set up the doors of it, the bolts of it, and the bars of it.

and above the gate of Ephraim, and by the old gate, and by the fish gate, and the tower of Hananel, and the tower of Hammeah, even to the sheep gate. And they stood still in the gate of the guard.
