'Maybe' in the Bible

"Please ask the Lord to come and help us, because King Nebuchadnezzar of Babylon is attacking us. Maybe the Lord will perform one of his miracles as in times past and make him stop attacking us and leave."

Maybe they will pay attention and each of them will stop living the evil way they do. If they do that, then I will forgo destroying them as I had intended to do because of the wicked things they have been doing.
