'Spare' in the Bible

Then should I yet have comfort; yea, I would harden myself in sorrow: let him not spare; for I have not concealed the words of the Holy One.

His archers compass me round about, he cleaveth my reins asunder, and doth not spare; he poureth out my gall upon the ground.

Though he spare it, and forsake it not; but keep it still within his mouth:

For God shall cast upon him, and not spare: he would fain flee out of his hand.

They abhor me, they flee far from me, and spare not to spit in my face.
