'Play the Harlot' in the Bible

And of thy garments thou didst take, and deck thy high places with divers colors, and play the harlot upon them: the like things shall not come, neither shall it be so.

And I said to her, Thou shalt abide for me many days; thou shalt not play the harlot, and thou shalt not be for another man: so will I also be for thee.
