'Emperor' in the Bible

But when Paul appealed to be held for trial by the Emperor, I ordered him to be kept in custody until I could send him to Caesar.”

Now I realized that he had not done anything deserving of death, but when he himself appealed to the Emperor, I decided to send him.

I have nothing definite to write to my lord about him. Therefore, I have brought him before all of you, and especially before you, King Agrippa, so that after this examination is over, I may have something to write.

Submit to every human authority because of the Lord, whether to the Emperor as the supreme authority

Honor everyone. Love the brotherhood. Fear God. Honor the Emperor.
