What does Isaiah 23:17 mean?
The prophet Isaiah has predicted the utter leveling of the port city of Tyre. This will be the Lord's judgment for her pride and self-glorification (Isaiah 23:1–12). Here, he describes her return to status as one of the world's premier shipping and trading cities after seventy years of being forgotten and ignored (Isaiah 23:15–16). However, Isaiah is not using the marketing language one might expect for Tyre's grand re-opening. He has described the city's return to her "wages" as a form of prostitution. He is presenting the city as one hiring themselves out to all the kingdoms of the world for their trading and shipping needs in the region of Phoenicia.This message isn't meant, at all, to imply that all successful business endeavors are like prostitution. Carrying out one's business with integrity, wisdom, and generosity is praised in the Bible. Something about Tyre's specific business practices, and her attitude of being willing to do anything for money, is what caused the people of this city to be compared to a prostitute.
Isaiah's prophecy about the city's return takes a surprisingly positive turn in the following verse (Isaiah 23:18).
