Scarlet Woman Meaning
The phrase a scarlet woman refers to a prostitute, an immoral woman, particularly one who commits adultery.
The phrase was first used in Revelation 17:5 where a sinful woman was described:
17:4 And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication:
17:5 And upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH. [King James Version; the New International Version uses "prostitutes" instead of "harlots"].
Example: She was the scarlet woman of the town.
