John Gill Commentary Isaiah 23:14

"Howl, ye ships of Tarshish; for your stronghold is laid waste." — Isaiah 23:14 (ASV)

Howl, you ships of Tarshish
As in (Isaiah 23:1) . (See Gill on Isaiah 23:1):

for your strength is laid waste ;
meaning Tyre, a strong seaport, where their ships were safe, and always found vent for their goods and merchandise; and so it was the strength and support of their country; but was now destroyed, and therefore was matter of lamentation and mourning.
