'Spare' in the Bible

if God indeed has not spared the natural branches; lest it might be he spare not thee either.

But if thou shouldest also marry, thou hast not sinned; and if the virgin marry, they have not sinned: but such shall have tribulation in the flesh; but I spare you.

But I call God to witness upon my soul that to spare you I have not yet come to Corinth.

I have declared beforehand, and I say beforehand as present the second time, and now absent, to those that have sinned before, and to all the rest, that if I come again I will not spare.
