Isaiah 23 is a prophecy about Tyre and Sidon. Tyre was the chief city of the Phoenician kingdom and closely allied with her sister city Sidon. These were settled by the Hittites who came from a powerful civilisation of the Hath-hi in Turkey. In the zenith of their power this kingdom rivalled the Egyptians and the Assyrians. The Phoenician’s were the greatest maritime nation of that time sending their navies as far as the Tarshish of the west – Great Britain. Verse 3 says that Tyre was the merchant navy of the world. Verse 6 explains how the mantle of maritime supremacy was relocated from Tyre to Great Britain who in the history of the last few hundred years has ruled the seas. Verses 11-14 speaks of the loss of naval greatness would be taken from her by the LORD in modern times. Tarshish. Verses 15-18 says that there would be a revitalisation of Tarshish’s powers after a 70 year epoch – the time of one monarch. We today are witnessing Great Britain reestablishing her old trading patterns with those nations of her commonwealth. This is at the close of the reign of Elizabeth 2 after a rule of seventy years.
