Ezekiel 33:31-33

ECB(i) 31 And they come to you as people approaching and they sit at your face as my people; and they hear your words, and work them not: for they work pantings with their mouth but their heart goes after their greedy gain: 32 and behold, you are to them as a song of pantings - of a beautiful voice strumming goodly on an instrument: for they hear your words, and they work them not. 33 And when this approaches - behold, it approaches then they know a prophet is among them.
