Harlot.
A woman given up to fornication: there were such as early as Genesis 38:15. The term is used metaphorically for unfaithfulness: "how is the faithful city become an harlot!" Isaiah 1:21; Ezekiel 16:31, Ezekiel 1:16. The mystic Babylon is designated "The mother of harlots," Revelation 17:5: not only unfaithful herself, but the mother of such.
