Accuser

a-kuz’-er: This word, not found in the Old Testament, is the rendering of two Greek words:

(1) kategoros, that is, a prosecutor, or plaintiff in a lawsuit, or one who speaks in a derogatory way of another (Ac 23:30,35; 25:16,18; Re 12:10);

(2) diabolos, meaning adversary or enemy. This word is rendered "accuser" in the King James Version and "slanderer" in the Revised Version (British and American) and the American Standard Revised Version (2Ti 3:3; Titus 2:3). According to the rabbinic teaching Satan, or the devil, was regarded as hostile to God and man, and that it was a part of his work to accuse the latter of disloyalty and sin before the tribunal of the former (see Job 1:6 ff; Zec 3:1 f; Re 12:10).
