thar'-a (Tharra): One of the two eunuchs, "keepers of the court," who with his companion Gabatha (Bigthan) formed a conspiracy against King Artaxerxes which was detected by Mordecai (Additions to Esther 12:1 = "Teresh" of Es 2:21; 6:2). Tharra and his companion were hanged. Josephus (BJ, II, vi, 4) calls him "Theodestes."
