Isaiah 1:8

The daughter of Zion, i.e. Zion, or Jerusalem; for these two names are promiscuously used of the same place; the name of daughter being frequently given to cities or countries. Thus the daughter of Babylon is put for Babylon itself, Psalms 137:8 Isaiah 47:1. In the same sense we read of the daughter of Tyre, Psalms 45:12, and of Zidon, Isaiah 23:12, and of Egypt, Jeremiah 46:11,24, and of Edom, Lamentations 4:21. Is left as a cottage in a vineyard as a lodge in a garden of cucumbers; is left solitary, all the neighbouring villages and country round about it being laid waste.
