Ezekiel 33:31-32

MLV(i) 31 And they come to you as the people come and they sit before you as my people. And they hear your words, but do not do them. For with their mouth they show much love, but their heart goes after their gain.
32 And behold, you are to them as a very lovely song of he who has a pleasant voice and can play well on an instrument. For they hear your words, but they do not do them.
