koun'-sil, koun'-siler (sumboulion): An assembly of advisers (Ac 25:12); a body of those taking counsel (see Schurer's Jewish People in the Time of Christ,I (1), 60). Distinguished from sunedrion, the supreme court of the Jews, by being of a less formal character, i.e. less of an institution. For "council" in the latter sense, its most frequent use, see SANHEDRIN. A councilor (Greek bouleutes) was a member of the Sanhedrin. Applied to Joseph of Arimathea (Mr 15:43; Lu 23:50). In the King James Version "counsellor."
