'Waster' in the Bible

Let mine outcasts dwell with thee, Moab; be thou a covert to them from the face of the waster. For the extortioner is at an end, the wasting hath ceased, the oppressors are consumed out of the land.

A vision of fear comes before my eyes; the worker of deceit goes on in his false way, and the waster goes on making waste. Up! Elam; to the attack! Media; I have put an end to her sorrow.

Behold, I have created the smith that bloweth the coals in the fire, and that bringeth forth an instrument for his work; and I have created the waster to destroy.
