This page provides an outline of Isaiah chapters 15 to 23 for your reference. The complete outline of Isaiah is spread over several pages.
Synopsis
Chapters thirteen to twenty-seven of Isaiah deliver oracles from the Lord to various nations, principally to Babylon who will rise up to crush Judah and destroy Jerusalem. Isaiah warns all these nations that God is over them and will take away their glory because of their sins. After delivering these oracles to particular nations, Isaiah then looks to the much more distant future, to the destruction of the whole world.
Oracles to Kingdoms
Philistia (of the Philistines) along the coastal plains wishes to be an ally of Judah against Assyria, but these old foes of Judah are doomed and their messengers will be told "The Lord has founded Zion"(Isa 14:28-32).
Moab is going to be destroyed by Assyria too. Moab’s pride leads to its downfall. God is compassionate to Moab and Judah is to accept the refugees into the kingdom (Isa 15-16). Note that Ruth David's great grandmother, was a Moabite.
Damascus and Ephraim (Syria and Israel) are going to fall to the Assyrians (Isa 17). Israel made an ally of Syria and together they attacked Judah. Ephraim was Israel’s main tribe. It was descended from Joseph. Damascus is Syria’s capital city.
Ethiopia also known as Cush, is a distant and powerful nation, yet even it will feel the blade of Assyria. Ethiopia will see Mount Zion (Jerusalem) stand, and send a gift of homage to its God the Lord of hosts (Isa 18).
Egypt is idolatrous and will not escape the Lord’s hand (Isa 19:1)..
There will be civil wars (Isa 19:2).
The demoralized people will resort to the occult for help (Isa 19:3).
Egypt will be conquered by Assyria (Isa 19:4).
The normal refreshing of the Nile will fail (Isa 19:5-7).
Industry along the Nile will be in ruin (Isa 19:8-10).
The princes of Zoan and Memphis (capital cities) will be deluded fools, heeding stupid advice, leading Egypt astray (Isa 19:11-15).
Egypt will be afraid of Judah (Isa 19:16-17).
Egypt’s great cities, even the City of the Sun, will turn to worshipping the Lord and he will send them a Saviour (Isa 19:18-21).
The Lord’s purpose in striking Egypt is to heal, not destroy (Isa 19:22).
A day is coming when Israel, Egypt, and Assyria, (Jew and Gentile) will all be united and blessed together as God’s people (Isa 19:23-25).
Isaiah goes naked for three years to symbolise the humiliation of Egypt and Ethiopia at the hand of the Assyrians (Isa 20).
Babylon to the north of Arabia, is the subject of a "harsh vision" for Isaiah. Babylon will rise to power and glory, but she will be punished for her idolatry. "Fallen, fallen is Babylon, and all the images of her gods are broken on the ground"(Isa 21:1-10)
Dumah (also called Seir and Edom) is to the east of Arabia. A watchman cries, "Morning comes, but also night". There is a day of respite for Edom, but the night of Assyrian terror is coming (Isa 21:11-12)
Arabia the nation of the desert wilderness, will not escape Assyria either. The splendour and might of its nomadic warrior tribes such as Kedar will vanish (Isa 21:13-17)
Jerusalem the capital of Judah will be under seige (Isa 22). God will place a good man in charge to help Jerusalem survive for the time being. Isaiah later records these events (Isa 36-37).
Tyre and Sidon"the market of nations" was a harbour city-state whose ships traded far afield and colonized distant places. (Isa 23:1-7)
God has planned to crush the pride of Tyre and Sidon (Isa 23:8-12).
When the Assyrians attack, Tyre’s king will flee north to the colony of Cyprus, but will find no rest (Isa 23:12).
Although Tyre will recover some power in the decline of the Assyrian empire, this will be short lived. The Babylonians will rise up and conquer the kingdom (Isa 23:13-14).
The kingdom will be "forgotten seventy years"(Isa 23:15-18).
