7:1-2 The kingdom of Israel and Syria joined together to take Jerusalem. They did not prevail in their attempt; but it was deeply hurtful that Israel would attack its brother-kingdom, Judah with another, non-family member.
7:3-6 Judah was afraid of the threat but the Lord spoke through Isaiah. God would cause their efforts against Judah to fail.
7:7-9 In fact, God continued and explained that Israel would be taken into captivity by their enemies. (They, like Judah, had become a corrupt kingdom).
7:10-12 God told Ahaz that he could ask for a sign, but Ahaz knew better. We are supposed to have faith in God without requiring proof or signs. Our strength is in our faith.
7:13-16 Unfortunately, the house of Judah had turned corrupt and it wearied God. In fact, God is wearied by corrupt actions done by humanity which is why, in this next verse, He promises the coming of Emmanuel, Jesus, God with us. Indeed Jesus' life was prophesied of in the Old Testament. God had a plan to save humanity since long ago!
7:17 But before that, Judah would go into captivity.
7:18-20 God promised to allow their enemies into their land to completely take over their kingdom.
7:21-22 Those who would remain in the land would subsist on very little, just enough to live on.
7:23-24 Indeed their enemies would take over easily, through politics rather than war, and the land would become desolate. For the land was a beautiful vineyard under the authority of God, but because of corruption it would become desolate.
