'Play the Harlot' in the Bible

And they shall no more sacrifice their sacrifices unto the he-goats, after which they play the harlot. This shall be a statute forever unto them throughout their generations.

then I will set my face against that man, and against his family, and will cut him off, and all that play the harlot after him, to play the harlot with Molech, from among their people.

And the soul that turneth unto them that have familiar spirits, and unto the wizards, to play the harlot after them, I will even set my face against that soul, and will cut him off from among his people.
