'Water gate' in the Bible

Moreover, the Nethinims dwelt in Ophel, to the place over against the water-gate towards the east, and the projecting tower.

And all the people assembled as one man in the street that was before the water-gate; and they spoke to Ezra the scribe to bring the book of the law of Moses, which the LORD had commanded to Israel.

And he read therein before the street that was before the water-gate from the morning until mid-day, before the men and the women, and those that could understand; and the ears of all the people were attentive to 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 street of the water-gate, and in the street of the gate of Ephraim.

And at the fountain-gate, which was over against them, they went up by the stairs of the city of David, at the ascent of the wall, above the house of David, even to the water-gate eastward.
