The aim of this passage is to cause us to learn the cause of Israel’s complete destruction and that the messiah would be based there.
Even though Israel would be destroyed, the lands of Zebulun and Naphtali would be the base for the Messiah (Isa 9:1-7)
The Messiah would be God.
After the lands of Zebulun and Naphtali had faced judgment at the hand of the Assyrians, they will be a glorious place and specifically Galilee. People who have lived in darkness will see the light and experience great joy.
They will be set free from oppression because a boy child will be born who rules everything. His name is Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. His rule and the peace He brings will last forever. He will be a descendant of David and will uphold justice and righteousness. All this will be accomplished because it is God’s intense desire to do so.
Matthew 16:15-17 He said to them, “But who do you say that I am?” Simon Peter replied, “You are the Christ, the Son of the living God.” And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
How does this passage help you understand the Gospels?
The northern kingdom would continue to face destruction because they were unrepentant (Isa 9:8-21)
Repentance, which is only possible through Jesus Christ, is the only way to escape God’s wrath.
This was the word of God given to Isaiah regarding the northern kingdom of Israel. After experiencing defeat they had arrogantly declared that they would recover. But God was not done because His anger had not been appeased yey. He would raise the Syrians and Philistines against them. All this is because, despite their suffering, the people had not turned back to God. God would destroy their leaders in one day. The elders, the men of honor, and the prophets would all be destroyed. Neither would God spare the youth or the fatherless and widows because all the people were wicked and spoke disgraceful things. Their own wickedness would destroy them. God’s anger would spare no one and the people would not spare each other. They would take destroy each other. After all this God’s anger would still not be satisfied.
Luke 13:1-5 There were some present at that very time who told him about the Galileans whose blood Pilate had mingled with their sacrifices. And he answered them, “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered in this way? No, I tell you; but unless you repent, you will all likewise perish. Or those eighteen on whom the tower in Siloam fell and killed them: do you think that they were worse offenders than all the others who lived in Jerusalem? No, I tell you; but unless you repent, you will all likewise perish.”
