| Clarke's Commentary on the Bible Thou shalt be a terror - Instead of being an object of adoration thou shalt be a subject of horror, and at last be destroyed with thy city, so that nothing but thy name shall remain. It was entirely burnt by Alexander the Great, as it had been before by Nebuchadnezzar.
Gill's Exposition of the Entire BibleAll they that know thee among the people shall be astonished at thee,.... At thy fall; that such a mighty city, and powerful prince, should be destroyed at once; that, from such a height of prosperity, they should be brought to so low an estate of adversity; this will be the astonishment of kings, merchants, and others, that knew the riches, power, and flourishing estate of Rome, as before observed: thou shalt be a terror; to the said persons, who will be afraid to come nigh for fear of the same torments and punishment, Revelation 18:10, or, though thou "hast been a terror"; or "terrors"; exceeding terrible to others in time past, yet now, as the Targum, "I will give thee (or make thee) as if thou wast not:'' and never shalt thou be any more; as thou hast been, or after thy last destruction; so mystical Tyre or Babylon shall be no more, when once destroyed, Revelation 18:21.
Geneva Study BibleAll they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more.

Matthew Henry's Concise Commentary28:1-19 Ethbaal, or Ithobal, was the prince or king of Tyre; and being lifted up with excessive pride, he claimed Divine honours. Pride is peculiarly the sin of our fallen nature. Nor can any wisdom, except that which the Lord gives, lead to happiness in this world or in that which is to come. The haughty prince of Tyre thought he was able to protect his people by his own power, and considered himself as equal to the inhabitants of heaven. If it were possible to dwell in the garden of Eden, or even to enter heaven, no solid happiness could be enjoyed without a humble, holy, and spiritual mind. Especially all spiritual pride is of the devil. Those who indulge therein must expect to perish. |
