Isaiah 7:3

Then said the LORD unto Isaiah, Go forth now to meet Ahaz, thou, and Shearjashub thy son, at the end of the conduit of the upper pool in the highway of the fuller's field;

Go forth now to meet Ahaz - Go forth out of the city, to the place where Ahaz was superintending the works for defense, and the cutting off of the water supply from the enemy, and the securing of it to the city. So ; .

Shear-jashub - i:e., a remnant shall return (). His very name (cf. 5:14; 8:3) was a standing memorial to Ahaz and the Jews that the nation should not, notwithstanding the general calamity (Isaiah 7:17; Isaiah 8:6), be utterly destroyed, (Isaiah 10:1; Isaiah 21:1; Isaiah 32:1).

At the end of the conduit of the upper pool - an aqueduct from the pool or reservoir for the supply of the city. At the foot of Zion was fount Shiloah (; ; ), called also (Gihon, on the west of Jerusalem (, "Hezekiak also stopped the upper water-course of Gihon, and brought it straight down to the west side of the city of David "). Two pools were supplied from it, the Upper, or Old (), or King's (), and the Lower (), which received he superfluous waters of the upper. The upper pool is still to be seen, about 700 yards from the Jaffa gate. The highway leading to the fuller's field, which was in a position near water, for the purposes of washing, previous to drying and bleaching the cloth, was probably alongside the aqueduct.
