But the Well gate builded Shallum the son of Colhozeh, the ruler of the fourth part of Mizphah; He builded it, covered it, and set on the doors, locks, and bars thereof, and the wall unto the pool of Siloam by the king's garden, unto the steps that go down from the city of David.

toward the Wellgate, and they went up over against them upon the steps of the city of David at the going up of the wall to the house of David, unto the Watergate Eastward.
