John Gill Commentary Isaiah 23:8

"Who hath purposed this against Tyre, the bestower of crowns, whose merchants are princes, whose traffickers are the honorable of the earth?" — Isaiah 23:8 (ASV)

Who hath taken this counsel against Tyre, the crowning
[city]
Which had a king over it, to whom it gave a crown; and which crowned its inhabitants with riches and plenty, and even enriched the kings of the earth, (Ezekiel 27:33) this is said as wondering who could lay a scheme to destroy such a city, or ever think of succeeding in it; who could take it into his head, or how could it enter into his heart, or who could have a heart to go about it, and still less power to effect the ruin of such a city, which was the queen of cities, and gave laws and crowns, riches and wealth, to others; surely no mere mortal could be concerned in this; see (Revelation 13:3Revelation 13:4) :

whose merchants [are] princes ;
either really such, for even princes and kings of the earth traded with her, (Ezekiel 27:21Ezekiel 27:33) or they were as rich as princes in other countries were:

whose traffickers [are] the honourable of the earth ;
made rich by trafficking with her, and so attained great honour and glory in the world; see (Revelation 18:3Revelation 18:15) .
