Ezekiel 33:30-33

30“As for you, son of man, the children of your people are talking about you beside the walls and in the doors of the houses; and they speak to one another, everyone saying to his brother, ‘Please come and hear what the word is that comes from the Lord.’

31So they come to you as people do, they sit before you as My people, and they hear your words, but they do not do them; for with their mouth they show much love, but their hearts pursue their own gain.

32Indeed you are to them as a very lovely song of one who has a pleasant voice and can play well on an instrument; for they hear your words, but they do not do them.

33And when this comes to pass—surely it will come—then they will know that a prophet has been among them.”
