(3) Go forth now to meet Ahaz . . .--At this crisis the prophet, already recognised as such, and gathering his disciples round him (Isaiah 8:16), is told to deliver a message to the king. He finds him halting between two opinions. He is making a show of resistance, but in reality he is not depending either on the protection of Jehovah, or the courage of his people, but on a plan of his own. Why should he not continue to pay tribute to Assyria, as Uzziah and Menahem (2Kings 15:19) had done, and write to Tiglath-pileser to attack the territories of the invading kings, as he actually did at a later stage in the war (2Kings 15:29)?

Thou and Shear-jashub thy son.--Assuming Isaiah 6 to give the first revelation of the idea of the "remnant," it would follow that the birth of the son whose name (Remnant returns--the return being both literal and spiritual--i.e., "is converted"), embodied a prophecy, must have followed on that revelation, and he was probably, therefore, at the time a stripling of sixteen or eighteen. It may be noted that Isaiah had in the history of Hosea 1, 2 the example of a prophet who, as his children were born, gave them names which were terribly or hopefully significant. Each child was, as it were, a sign and portent (Isaiah 8:18). The fact that the mother of his children was herself a prophetess (Isaiah 8:3), sharing his hopes and fears, gives a yet deeper interest to the fact.

At the end of the conduit . . .--The king was apparently superintending the defensive operations of the siege, probably cutting off the supply of water outside the walls, as Hezekiah afterwards did (2Chronicles 32:3-4). The "upper pool" has been identified with the Upper Gihon pool (Birket-el-Mamilla) or the "dragon's well" of Nehemiah 2:13. A lower pool meets us in Isaiah 22:9. The "fuller's field" was near En-rogelim (Isaiah 36:2; 2Samuel 17:17).

Verse 3. - Thou, and Shear-Jashub thy son. The name Shear-Jashub, "a remnant shall return," may have been given to Isaiah's son by revelation, as Ewald thinks it was; or Isaiah may have given it to testify his faith both in the threats and in the promises of which he had been made the mouth-piece. The command to take him with him on the present occasion was probably given on account of his name, that the attention of Ahaz might be called to it. The conduit of the upper pool is mentioned also in 2 Kings 18:17. It was probably a subterranean duct which brought water into the city from the high ground outside the Damascus gate. Ahaz may have visited it in order to see that it was made available for his own use, but not for the enemy's (comp. 2 Chronicles 32:3, 4, 30; Isaiah 22:9, 11).

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.Then said the Lord unto Isaiah,.... The prophet, the inspired penman of these prophecies, that go by his name; what follows, the Lord said unto him in vision, or by an articulate voice, or by an impulse on his mind:

go forth now to meet Ahaz; the prophet was in the city of Jerusalem, and Ahaz was without, as appears by the place after mentioned, where he was to meet him; perhaps Ahaz was at his country house, which, upon the news brought him of the designs of his enemies, he leaves, and betakes himself to Jerusalem, his metropolis, and fortified city, where he might be more safe; or he had been out to reconnoitre the passes about Jerusalem, and give orders and directions for the strengthening and keeping of them:

thou, and Shearjashub thy son: whose name signifies "the remnant shall return", and who was taken with the prophet, to suggest either that the remnant that were left of the former devastations by those two kings ought to return to the Lord by repentance; or that though the people of Judah should hereafter be carried captive by the Assyrians, yet a remnant should return again. The Targum interprets this not of Isaiah's natural son, but of his disciples; paraphrasing it thus,

"thou, and the rest of thy disciples, who have not sinned, and are turned from sin:''

at the end of the conduit of the upper pool; for there was an upper pool and a lower one; see Isaiah 22:9 this was outside the city, and is the same place where Rabshakeh afterwards stood, and delivered his blasphemous and terrifying speech, 2 Kings 18:17,

in the highway of the fuller's field; where they washed and dried their garments, and whitened them; the pool, conduit, and field, being fit for their purpose.
