Phoenicia was the commercial power of the Mediterranean world in ancient times, and Tyre and Sidon were its chief cities. With a monopoly on shipping throughout the Mediterranean, Phoenicia was very wealthy, cultured and esteemed by all with whom she conducted business. Her wealth bought her security. Tyre was considered particularly safe because it occupied an island off the coast and built security measures virtually impossible to breach from the water. No enemy dared to bother with that fortress. However, the fulfillment of the prophecy about the destruction of Tyre’s stronghold was fulfilled in 573 BC under Nebuchadnezzar king of Babylon, and again in 332 B.C. by Alexander the Great. As Isaiah 23 predicted, there was great anguish in the Mediterranean world at the fall of Tyre; anyone was vulnerable if Tyre could be breached.
Chapters 24 – 27 are pretty straightforward. I encourage you to read these chapters prayerfully, asking God to direct your thoughts to where He wants to teach you, and making a little time to contemplate what He shows you and what more He wants to show you.
