'Unsparingly' in the Bible

He that smote the peoples in wrath with a relentless stroke, he that ruled the nations in anger, is persecuted unsparingly.

And he shall break it as the breaking of a potter's vessel, that is broken in pieces unsparingly; and in the pieces of it there shall not be found a sherd to take fire from the hearth, or to scoop water out of the cistern.
