'Fight' in the Bible

Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.

I therefore so run, as not uncertainly; so fight I, as not beating the air:

Fight the good fight of the faith, lay hold on the life eternal, whereunto thou wast called, and didst confess the good confession in the sight of many witnesses.

I have fought the good fight, I have finished the course, I have kept the faith:

Ye lust, and have not: ye kill, and covet, and cannot obtain: ye fight and war; ye have not, because ye ask not.
