Ezekiel 33:31-33

JPS_ASV_Byz(i) 31 and come unto thee as the people cometh, and sit before thee as My people, and hear thy words, but do them not - for with their mouth they show much love, but their heart goeth after their covetousness; 32 and, lo, thou art unto them as a love song of one that hath a pleasant voice, and can play well on an instrument; so they hear thy words, but they do them not - 33 when this cometh to pass - behold, it cometh - then shall they know that a prophet hath been among them.'
