John Gill Commentary Ezekiel 26:18

"Now shall the isles tremble in the day of thy fall; yea, the isles that are in the sea shall be dismayed at thy departure." — Ezekiel 26:18 (ASV)

Now shall the isles tremble in the day of your fall
The isles near unto it, the isles of the Mediterranean sea; the inhabitants of them, the merchants who from thence traded with Tyre, the seafaring men of those places; partly on account of losses sustained hereby, and partly through fear of the same calamities coming upon themselves; see (Revelation 18:11Revelation 18:15Revelation 18:17) :

Indeed, the isles that are in the sea shall be troubled at your departure; as at the cry of the wounded, and the number of the slain; so on account of those that should be carried away captive by the Babylonians; as well as at the departure of those that should be obliged to fly to other colonies, (Isaiah 23:6) , so that, upon one account or another, it shall be entirely stripped of its inhabitants.
