'Fish gate' in the Bible

Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he encircled Ophel [with it], and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah.

The fish gate did the sons of Hassenaah build; they laid its beams, and set up its doors, its bolts, and its bars.

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.

In that day, says Yahweh, there will be the noise of a cry from the fish gate, a wailing from the second quarter, and a great crashing from the hills.
