Ezekiel 33:31-35

And they come to you as people come, and sit before you as My people and hear your words, but they do not do them; for they do the lustful desires expressed by their mouth, and their heart follows their unlawful gain.

And behold, you are to them like a love song by one who has a beautiful voice and plays well on an instrument; for they hear your words but they do not practice them.

So when it comes—as it certainly will—then they will know that a prophet has been among them.”
