Ezekiel 33:30-33

30And as for thee, son of man, the children of thy people keep talking of thee by the walls and in the doors of the houses, and speak one to another, every one to his brother, saying, Come, I pray you, and hear what is the word that cometh forth from Jehovah. 31And they come unto thee as a people cometh, and they sit before thee [as] my people, and they hear thy words, but they do them not; for with their mouth they shew much love, [but] their heart goeth after their dishonest gain. 32And behold, thou art unto them as a lovely song, a pleasant voice, and one that playeth well on an instrument; and they hear thy words, but they do them not. 33And when this cometh to pass (behold, it will come), then shall they know that a prophet hath been among them.
