Isaiah 47:10

In the Bible, ‘fool’ often means someone who has no thought about God (see Psalms 14:1 and Luke 12:13-21).

No help for Babylon

v12 ‘Of course, you may decide to carry on with your black (wicked) magic. You may continue to use evil practices. You have depended on them all your life. You may even hope that one day they might possibly help you to avoid trouble. Or perhaps you think that you could use them to frighten other people. v13 The vast quantity of advice that you receive has worn you out. Some comes from those who study the sky. Some comes from those who look for the future in the stars. And some comes from those who announce month by month what to expect. Let all these people rise and rescue you! v14 Look, they are no better than straw that the fire burns. They cannot rescue even themselves from the flames. They provide neither coals to warm anybody, nor a pleasant fire to sit near. v15 People like that will not help you. All your life you have paid them for their advice. But now they are no use to you. In this emergency they only want to save themselves. None of them will stay to try to save you.’
