Ezekiel 33:30-32

30“Now as for you, son of man, the children of your people are talking about you by the walls and in the doorways of the houses. Each one speaks to one another, each saying to his brother: ‘Come now, hear what message is coming forth from Adonai!’

31So 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 with their mouth they express doting love, but their heart goes after their own dishonest gain.

32Look, you are like a love song to them, one who has a beautiful voice and can play well on an instrument. They hear your words, but do not practice them.
