What does Isaiah 23:18 mean?

But her profits and earnings will be set apart for the Lord. They won’t be stored up or hoarded. Instead, her wealth will go to those who serve the Lord, so they’ll have plenty of food and fine clothes. Isaiah 23:18 - Modern Text Bible

(In the end, Tyre’s wealth will be used for God’s purposes, not just for selfish gain. Those who serve God will benefit from what Tyre brings in.)
