Isaiah 23

Isaiah spoke of a day that God was planning. It had not yet come to pass. On that future day Tyre will be destroyed. The ramifications to the people and merchants of Tyre are obvious. But what about the other nations who traded through Tyre? Would they not feel the impact of such a loss? Of course they would. That is why all the nations will mourn. Even in ancient days God's actions addressed more than a single people. His rebuke would be poured out on all people who share in Tyre's immorality. The economic  impact of God's rebukes can cause global problems. And only believers will understand the divine work of such actions.
