Thematic Bible: Professing but not practising

And they come in unto thee as the coming in of a people, And they sit before thee -- My people, And have heard thy words, and they do them not, For doting loves with their mouth they are making, After their dishonest gain their heart is going. And lo, thou art to them as a singer of doting loves, A pleasant voice, and playing well on an instrument, And they have heard thy words, and they are not doing them.
