Deputy

in 1 Kings 22:47 , means a prefect; one set over others. The same Hebrew word is rendered "officer;" i.e., chief of the commissariat appointed by Solomon ( 1 Kings 4:5 , etc.).

In Esther 8:9 ; 9:3 (RSV, "governor") it denotes a Persian prefect "on this side" i.e., in the region west of the Euphrates. It is the modern word pasha .

In Acts 13:7 Acts 13:8 Acts 13:12 ; 18:12 , it denotes a proconsul; i.e., the governor of a Roman province holding his appointment from the senate. The Roman provinces were of two kinds, (1) senatorial and (2) imperial. The appointment of a governor to the former was in the hands of the senate, and he bore the title of proconsul (Gr. anthupatos). The appointment of a governor to the latter was in the hands of the emperor, and he bore the title of propraetor (Gr. antistrategos).
