'Appeal to Caesar' in the Bible

Therefore, if I am guilty and have committed anything worthy of death, I do not try to escape death; but if there is nothing to the accusations which these men are bringing against me, no one can hand me over to them. I appeal to Caesar (Emperor Nero).”

But when the Jews objected [to my release], I was forced to appeal to Caesar (Emperor Nero), not because I had any charge to make against my nation.
