One of two eunuchs whose plot against Artaxerxes (the Ahasuerus, i.e. Xerxes, of canonical Est.) was discovered and frustrated by Mardocheus (Mordecai). Ad. Est 12:1. In Es 2:21 he is called Bigthan and in Es 6:2 Bigthana.
During those days while Mordecai was sitting at the King's Gate, Bigthan and Teresh, two eunuchs who guarded the [king's] entrance, became infuriated and tried to assassinate King Ahasuerus.
They found the written report of how Mordecai had informed on Bigthana and Teresh, two eunuchs who guarded the [king's] entrance, when they planned to assassinate King Ahasuerus.
Mordecai the Jew was second only to King Ahasuerus, famous among the Jews, and highly popular with many of his relatives. He continued to seek good for his people and to speak for the welfare of all his kindred.
