'Water gate' in the Bible

(Now the Nethinim dwelt in Ophel, unto the place over against the water gate toward the east, and the tower that standeth out.)

And all the people gathered themselves together as one man into the broad place that was before the water gate; and they spake unto Ezra the scribe to bring the book of the law of Moses, which Jehovah had commanded to Israel.

And he read therein before the broad place that was before the water gate from early morning until midday, in the presence of the men and the women, and of those that could understand; and the ears of all the people were attentive unto the book of the law.

So the people went forth, and brought them, and made themselves booths, every one upon the roof of his house, and in their courts, and in the courts of the house of God, and in the broad place of the water gate, and in the broad place of the gate of Ephraim.

And by the fountain gate, and straight before them, they went up by the stairs of the city of David, at the ascent of the wall, above the house of David, even unto the water gate eastward.
