'Played the Harlot' in the Bible

And yet they did not listen to their judges; for they played the harlot after other gods and bowed down to them; they soon turned aside from the way in which their fathers had walked, who had obeyed the commandments of the LORD, and they did not do so.

And Gideon made an ephod of it and put it in his city, in Ophrah; and all Israel played the harlot after it there, and it became a snare to Gideon and to his family.

As soon as Gideon died, the people of Israel turned again and played the harlot after the Ba'als, and made Ba'al-be'rith their god.
