'Play the Harlot' in the Bible

then they shall bring the girl out to the door of her father's house, and the men of her city shall stone her with stones so that she dies, because she has done foolishness in Israel to play the harlot in her father's house. So you shall put evil away from among you.

They say, If a man puts away his wife, and she goes from him and will be for another man, will he return to her again? Would not that land be greatly defiled? But you play the harlot with many lovers; yet come back to Me, says Jehovah.
