Easton's Bible Dictionary (1897)
Gab Baitha, i.e., “the ridge of the house” = “the temple-mound,” on a part of which the fortress of Antonia was built. This “temple-mound” was covered with a tesselated “pavement” (Gr. lithostroton, i.e., “stone-paved”). A judgement-seat (bema) was placed on this “pavement” outside the hall of the “praetorium” (q.v.), the judgment-hall (John 18:28; 19:13).
Smith's Bible Dictionary (1863)
(elevated; a platform) the Hebrew or Chaldee appellation of a place, also called “Pavement,” where the judgment-seat or bema was planted, from his place on which Pilate delivered our Lord to death. (John 19:13) It was a tessellated platform outside the praetorium, on the western hill of Jerusalem, for Pilate brought Jesus forth from thence to it.
