'Unsparingly' in the Bible

Then he struck them without mercy, a great slaughter; and he went down and lived in the cleft of the rock of Etam.

“For it will hurl [thunderbolts of God’s wrath] at him unsparingly and without compassion;He flees in haste from its power.

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.
