Isaiah uses a question to mock Tyre. The word "this" refers to God's plans to destroy Tyre which Isaiah described in 23:1-7. Also, "Tyre" refers to the people who live in Tyre. This rhetorical question can be translated as a statement. AT: "It was Yahweh who has planned to destroy the people of Tyre ... of the earth." (See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-metonymy]])
Here "crown" refers to the power a person has as a ruler over people. AT: "who gives people power to rule over others" (See: [[rc://en/ta/man/translate/figs-metonymy]])
The merchants are compared to princes to emphasize how much power they had when they went to different lands. AT: "whose merchants are like princes" (See: [[rc://en/ta/man/translate/figs-metaphor]])
This can be stated in active form. AT: "whose traders the people of the earth give the highest honors" (See: [[rc://en/ta/man/translate/figs-activepassive]])
