'Water gate' in the Bible

(Now the Nethinim lived in Ophel, to the place over against the water gate toward the east, and the tower that stands out.)

All the people gathered themselves together as one man into the broad place 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.

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 who could understand; and the ears of all the people were attentive to the book of the law.

So the people went out, and brought them, and made themselves booths, everyone on the roof of his house, and in their courts, and in the courts of God's house, and in the broad place of the water gate, and in the broad place of the gate of Ephraim.

By the spring 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 to the water gate eastward.
