"Hey, check it out! It's Isaiah 4! The Lord has promised Jerusalem will be restored, so the prophet Isaiah is feeling pretty positive about the future. He says that when the city is restored, it'll be a sign of God's protection. He also says that the city will be surrounded by a cloud of smoke, which is both a good thing and a bad thing. On the one hand, it'll keep out the enemies, but on the other hand, it'll trap the city inside a giant foggy prison. Yikes! Then he goes on to talk about how the Lord will make sure that the city is well-protected and will be safe from its enemies. In the end, everything will be alright, so don't worry, folks!"
