This same Hezekiah also stopped the upper water course of Gihon,.... Which Procopius Gazeus says was the same with Siloam, and which it seems had two streams, and this was the upper one; Mr. Maundrell says (c), the pool of Gihon"lies about two furlongs without Bethlehem gate westward; it is a stately pool, one hundred and six paces long, and sixty seven broad, and lined with wall and plaster, and was, when we were there, well stored with water:" and brought it straight down to the west side of the city of David; through canals under the plain of the city of David; as the Targum, by a subterraneous passage; and Siloam, as Dr. Lightfoot (d) observes from Josephus, was behind the west wall, not far from the corner that pointed toward the southwest: and Hezekiah prospered in all his works; natural, civil, and religious, Ch2 31:21.
