Jesaja 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).

This chapter is concerning Tyre, an ancient wealthy city, situated upon the sea, and for many ages one of the most celebrated cities for trade and merchandise in those parts of the world. The lot of the tribe of Asher bordered upon it. See Jos 19:29, where it is called "the strong city Tyre." We seldom find it a dangerous enemy to Israel, but sometimes their faithful ally, as in the reigns of David and Solomon; for trading cities maintain their grandeur, not by the conquest of their neighbours, but by commerce with them. In this chapter is foretold, I. The lamentable desolation of Tyre, which was performed by Nebuchadnezzar and the Chaldean army, about the time that they destroyed Jerusalem; and a hard task they had of it, as appears Eze 29:18, where they are said to have "served a hard service against Tyre," and yet to have no wages (Isa 23:1-14). II. The restoration of Tyre after seventy years, and the return of the Tyrians out of their captivity to their trade again (Isa 23:15-18).

23:17 Metaphorically, Tyre was a prostitute because of its indifferent willingness to sell anything to anyone (cp. Rev 17:2; 18:3, 12-13).
