Scholars explain that "ships of Tarshish" likely refers not to a specific origin but to the largest class of vessels, similar to how we might say "ocean liner." These ships were the backbone of Tyre's prosperity. A key phrase is debated, with interpretations suggesting these ships were Tyre's "bulwarks" (defenses), "caravans" (commerce), or "princes" (chief traders), all highlighting their central role in Tyre's glory.
