Dict: easton - Conduit

easton:

Conduit @ a water-course or channel kjv@Job:38:25). The "conduit of the upper pool" kjv@Isaiah:7:3) was formed by Hezekiah for the purpose of conveying the waters from the upper pool in the valley of Gihon to the west side of the city of David ( kjv@2Kings:18:17 kjv@2Kings:20:20; kjv@2Chronicals:32:30). In carrying out this work he stopped "the waters of the fountains which were without the city" i.e., "the upper water-course of Gihon", and conveyed it down from the west through a canal into the city, so that in case of a siege the inhabitants of the city might have a supply of water, which would thus be withdrawn from the enemy. (
See SILOAM.) There are also the remains of a conduit which conducted water from the so-called "Pools of Solomon," beyond Bethlehem, into the city. Water is still conveyed into the city from the fountains which supplied these pools by a channel which crosses the valley of Hinnom.
