The Lord addresses the people. Do not listen to the words of your preachers, your prophets, he tells them, because they have nothing useful to say and indeed their words are harmful and destructive and need to be avoided.
Charismatic movement is characterised by those whose message comes from their own imaginations. They deceive each other and they even deceive themselves, but there remains an awareness that this is something worked up. Self-deception starts with a sense that there is deception involved, however hard the mind works to explain it. They do not know how to hear a genuine message from the Lord, and so they come up with something in its place which cannot help anyone.
