C. F. Keil and Franz Delitzsch on Isaiah 23:17

Isa 23:17

When it begins again to make love to all the world, it will get rich again from the gain acquired by this worldly intercourse. “And it will come to pass at the end of the seventy years: Jehovah will visit Tzor, and she comes again to her hire, and commits prostitution with all the kingdoms of the earth on the broad surface of the globe.” Such mercantile trading as hers, which is only bent upon earthly advantages, is called zânâh, on account of its recognising none of the limits opposed by God, and making itself common to all the world, partly because it is a prostitution of the soul, and partly because from the very earliest times the prostitution of the body was also a common thing in markets and fairs, more especially in those of Phoenicia (as the Phoenicians were worshippers of Astarte). Hence the gain acquired by commerce, which Tyre had now secured again, is called 'ethnân (Deu 23:19), with a feminine suffix, according to the Masora without mappik (Ewald, §247,a).
