'Destroyer' in the Bible

Let the fugitives from Moab settle among you; be a shelter to them from the destroyer. When the oppressor comes to an end, and destruction has ceased, and the marauder has vanished from the land,

"How terrible it will be for you, destroyer, you who have not been destroyed yourself! And how terrible it will be for you, traitor, one whom people have not betrayed! When you have sunk so low in destroying others, you will be destroyed; and when you have finished betraying, they will betray you."
