'Office' in the Bible

"For in the Book of Psalms it is written, "Let his estate be desolate, and let no one live on it,' and, "Let someone else take over his office,'

to serve in this office of apostle, from which Judas left to go to his own place."

But after two years had passed, Felix was succeeded [in office] by Porcius Festus; and wishing to do the Jews a favor, Felix left Paul imprisoned.
