'Fountain' in the Bible

Then I went on to the gate of the fountain, and to the king's pool: but there was no place for the beast that was under me to pass.

But the gate of the fountain repaired Shallun the son of Colhozeh, the ruler of part of Mizpah; he built it, and covered it, and set up the doors thereof, the locks thereof, and the bars thereof, and the wall of the pool of Siloah by the king's garden, and unto the stairs that go down from the city of David.

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