'Water gate' in the Bible

(Now the Nethinim dwelt in Ophel, even over against the water-gate toward the east, and the tower which lies out.)

all the people gathered together as one man to the open place that was before the water-gate; and they spoke to Ezra the scribe to bring the book of the law of Moses, which Jehovah had commanded Israel.

And he read in it before the open place that was before the water-gate from the morning until midday, in presence of 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.

And the people went forth and brought them, and made themselves booths, everyone upon the roof of his house, and in their courts, and in the courts of the house of God, and in the open space of the water-gate, and in the open space of the gate of Ephraim.

And at the fountain-gate, and 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.
