'Fountain' in the Bible

Then I passed on to the Fountain Gate and the King’s Pool, but there was no place for my mount to pass.

Shallum the son of Col-hozeh, the official of the district of Mizpah, repaired the Fountain Gate. He built it, covered it and hung its doors with its bolts and its bars, and the wall of the Pool of Shelah at the king’s garden as far as the steps that descend from the city of David.

At the Fountain Gate they went directly up the steps of the city of David by the stairway of the wall above the house of David to the Water Gate on the east.
