'Spare' in the Bible

“O look away from me, that I may smile and again know joyBefore I depart and am no more.”

You, O Lord God of hosts, the God of Israel,Arise to punish all the nations;Spare no one and do not be merciful to any who treacherously plot evil. Selah.

He leveled a path for His anger [to give it free run];He did not spare their souls from death,But turned over their lives to the plague.

Let the groaning and sighing of the prisoner come before You;According to the greatness of Your power keep safe those who are doomed to die.
