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

(e) That is to say, the rest will return which name Isaiah gave his son, to signify that the rest of the people would return out of their captivity.

Wesley's Notes

7:3 Thy son - Whose very name carried in it a sign and pledge of the promised deliverance, signifying, The remnant shall return. Fuller's field - Whither he probably went to take care about the waters which thence were brought into the city, to secure them to himself, or keep them from the enemy, as Hezekiah afterward did, 2Chron 32:3,4.

Jamieson-Fausset-Brown Bible Commentary

3. 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 securing it to the city. So Isa 22:9; 2Ch 32:4.

Shearjashub-that is, A remnant shall return (Isa 6:13). His very name (compare Isa 7:14; Isa 8:3) was a standing memorial to Ahaz and the Jews that the nation should not, notwithstanding the general calamity (Isa 7:17-25; Isa 8:6-8), be utterly destroyed (Isa 10:21, 22).

conduit-an aqueduct from the pool or reservoir for the supply of the city. At the foot of Zion was Fount Siloah (Isa 8:6; Ne 3:15; Joh 9:7), called also Gihon, on the west of Jerusalem (2Ch 32:30). Two pools were supplied from it, the Upper, or Old (Isa 22:11), or King's (Ne 2:14), and the Lower (Isa 22:9), which received the superfluous waters of the upper. The upper pool is still to be seen, about seven hundred yards from the Jaffa gate. The highway leading to the fullers' 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.

Matthew Henry's Concise Commentary

7:1-9 Ungodly men are often punished by others as bad as themselves. Being in great distress and confusion, the Jews gave up all for lost. They had made God their enemy, and knew not how to make him their friend. The prophet must teach them to despise their enemies, in faith and dependence on God. Ahaz, in fear, called them two powerful princes. No, says the prophet, they are but tails of smoking firebrands, burnt out already. The two kingdoms of Syria and Israel were nearly expiring. While God has work for the firebrands of the earth, they consume all before them; but when their work is fulfilled, they will be extinguished in smoke. That which Ahaz thought most formidable, is made the ground of their defeat; because they have taken evil counsel against thee; which is an offence to God. God scorns the scorners, and gives his word that the attempt should not succeed. Man purposes, but God disposes. It was folly for those to be trying to ruin their neighbours, who were themselves near to ruin. Isaiah must urge the Jews to rely on the assurances given them. Faith is absolutely necessary to quiet and compose the mind in trials.
