What does Isaiah chapter 23 mean?
Isaiah's prophecy against the city of Tyre is the final last of his series of oracles against the nations nearby Judah. The point of these oracles has been to show Judah that none of these nations—who they may have been tempted to turn to for help— was strong enough to protect them. Even the great wealth and natural defenses of a city like Tyre would not be enough to protect it from destruction.Tyre was a great port city on the Mediterranean coast, about 12 miles, or 19 kilometers, north of the modern border of Israel. During Isaiah's time, it was a thriving center of trade and shipping. The city's natural defenses made it difficult to conquer. Twin islands stood not far off the coast, and natural deep-water harbors made it easily accessible to boats of all sizes from around the world.
This oracle about Tyre's future destruction begins by describing the reaction of various groups. They are responding to the idea that this ancient and powerful city has been wiped out. It is not clear which destruction of Tyre Isaiah is pointing to in this chapter. However, most commentators suggest it is either an attack by the Assyrians during Isaiah's era or the decimation of the city by Alexander the Great in 332 BC.
The prophecy calls for the ships of Tarshish to wail and mourn because everything on Tyre has been destroyed. This includes everything from the harbor to the houses. The sailors get the news when putting in at the large island of Cyprus, about 75 miles, 120 kilometers, off the Phoenician coast. The ships of Tarshish would sail from one end of the Mediterranean to the other. Isaiah pictures these sailors returning from a long voyage only to find their home port obliterated (Isaiah 23:1).
Next, the oracle instructs the inhabitants of the coast, including Sidon to be still, or to mourn, because the source of their enrichment is gone. No more would Egypt's grain be arriving to provide sustenance and revenue. The sea itself seems to grieve the loss of the sailors since it has no children of its own. Egypt's farming economy will be devastated. The people of Tarshish, likely in modern-day Spain, will wail, unable to believe the ancient city has been destroyed (Isaiah 23:2–7).
Regarding who has caused this destruction, Isaiah is clear: It is the Lord of hosts. God has defiled the pompous pride of Tyre and turned its honor to dishonor. He has stretched His hand over the sea, showing it belongs to Him and not to the Canaanite sea god. He has given the command to destroy all the strongholds of Canaan. He tells Sidon, 25 miles, or 40 kilometers, north of Tyre, that the party is over. Running away won't help. The Lord God's judgment has come (Isaiah 23:8–12).
As evidence that the destruction is coming, the Lord tells the people of Tyre to remember Babylon, in the land of the Chaldeans. That once great city and its people have been reduced to nothing since the Lord sent the Assyrians. This invading army set a siege on the city and destroyed it. Tyre, too, will be destroyed (Isaiah 23:13–14).
The city of Tyre will be forgotten, a shell of its former self, for 70 years. When it returns it will make its wages as a prostitute to the all the kingdoms on the face of the earth. This time, however, the Lord declares that her merchandise and wages will be used to supply abundance for the Lord's people. The city's wealth will not just be stored up in Tyre (Isaiah 23:15–18).
