'Spare' in the Bible

And I will dash them one against another, even the fathers and the sons together, saith the LORD: I will not pity, nor spare, nor have mercy, but destroy them.

And afterward, saith the LORD, I will deliver Zedekiah king of Judah, and his servants, and the people, and such as are left in this city from the pestilence, from the sword, and from the famine, into the hand of Nebuchadrezzar king of Babylon, and into the hand of their enemies, and into the hand of those that seek their life: and he shall smite them with the edge of the sword; he shall not spare them, neither have pity, nor have mercy.

Put yourselves in array against Babylon round about: all ye that bend the bow, shoot at her, spare no arrows: for she hath sinned against the LORD.

Against him that bendeth let the archer bend his bow, and against him that lifteth himself up in his brigandine: and spare ye not her young men; destroy ye utterly all her host.
