'Destroyer' in the Bible

“Let the outcasts of Moab stay with you;Be a hiding place to them from the destroyer.”For the extortioner has come to an end, destruction has ceased,Oppressors have completely disappeared from the land.

A harsh vision has been shown to me;The treacherous one still deals treacherously, and the destroyer still destroys.Go up, Elam, lay siege, Media;I have made an end of all the groaning she has caused.

Woe to you, O destroyer,While you were not destroyed;And he who is treacherous, while others did not deal treacherously with him.As soon as you finish destroying, you will be destroyed;As soon as you cease to deal treacherously, others will deal treacherously with you.

“Behold, I Myself have created the smith who blows the fire of coalsAnd brings out a weapon for its work;And I have created the destroyer to ruin.
