'Play' in the Bible

Therefore, say to the house of Israel, ‘Thus says the Lord God, “Will you [exiles] defile yourselves in the same manner as your fathers? And will you prostitute yourselves before their loathsome and heinous things?

“Then I said concerning the one (Oholah) worn out by adulteries, ‘Will they now commit adultery with her when she is like this?’

Behold, you are to them like a love song by one who has a pleasant voice and plays well on a stringed instrument [merely to entertain them]; for they hear your words but do not practice them.
