What does Ezekiel 33:27 mean?

Tell them this: 'This is what the Lord says: As surely as I live, those left in the ruins will die by the sword. Those out in the open fields I'll give to wild animals to be eaten. Those hiding in caves and shelters will die from disease.' Ezekiel 33:27 - Modern Text Bible
