In the time of Solomon harlots appeared openly in the streets, and he solemnly warns against association with them (Proverbs 7:12; 9:14. See also Jeremiah 3:2; Ezekiel 16:24,25,31).

To commit fornication is metaphorically used for to practice idolatry (Jeremiah 3:1; Ezekiel 16:15; Hos. throughout); hence Jerusalem is spoken of as a harlot (Isaiah 1:21).
In the New Testament the Greek pornai, plural, "harlots," occurs in Matthew 21:31,32, where they are classed with publicans; Luke 15:30; 1 Corinthians 6:15,16; Hebrews 11:31; James 2:25. It is used symbolically in Revelation 17:1,5,15,16; 19:2.
