v1-2: Some parts of Isaiah's ministry are linked more closely with the history of his day. Aram (Syria) and Israel (also called Ephraim) had allied themselves against Judah. But God had been merciful to His people, and they could not overpower the city, 2 Kings 16.5.
v3: Isaiah's first son bore the name of a prophecy, "A remnant will return." Thus, Isaiah's message to the people remained in the person of his son.
v4-6: The message to Ahaz the king, "Don't be afraid. Do not lose heart." The opposing armies, the two firebrands, would not succeed in their ambition to divide Judah. Isaiah refers to a conspiracy amongst the surrounding nations, to replace Ahaz with the line of Tabeel – God’s promise was that this conspiracy would fail.
v7-9: The promise that Rezin and Pekah would not be successful was not due to Judah's godliness, but rather their ungodliness, compare Deut 9.5-6. God's promises to His people rested more on His faithfulness than on theirs.
During Pekah's reign in Israel, Assyria began to capture parts of the nation, 2 Kings 15.29. Within 65 years, Israel was totally defeated by Assyria.
There was also a challenge to Ahaz here, about his standing firm in his faith in God. He might miss out on personal blessing, but God's promises would not fail. When we retain fear and doubt, we fail to move in faith.
v10-13: See 2 Kings 16-2.4; Ahaz was disobedient. He tried to provide a spiritual response to excuse his disobedience. Even in the O.T. God was seeking to teach His people about His character, rather than imposing a strict set of rules.
v14: The Lord God would give the sign of the virgin anyway, irrespective of Ahaz's unbelief.
v15: A reference to Christ's perfect righteousness and discernment.
v16-17: The land that Ahaz dreaded was the confederation of Israel and Aram, see 8.4. They had produced great fear in Judah, as the people were shaken (v2). Yet those lands would be laid waste; fulfilled 2 Kings 16.9; 17.5-6. There was some fulfilment through Hezekiah, but the greater fulfilment is in Christ. See chapters 36-39, which describe Assyria's later attack on Judah.
v18-19: The fly in Egypt, the bee in Assyria; referring to the armies of those nations. The Lord God would whistle, see in 5.26, and those armies would have to come.
v20: The army of Assyria, hired by the Lord, to shave (depopulate) the area. The Lord has to hire a nation of judgment, because His own people were full or mercy.
v21-22: Since there would be fewer people, the available food would be more plentiful.
v23-25: The land of Judah would, however, become desolate and fruitless, with domesticated animals running loose. This desolation reflected the spiritual poverty of the people.
