Severe, a eunuch or chamberlain in the palace of Ahasuerus, who conspired with another to murder him. The plot was detected by Mordecai, and the conspirators were put to death (Esther 2:21; 6:2).
Teresh
Teresh is a minor figure in the book of Esther, and his story is short. He and Bigthan were the king’s chamberlains, keepers of the door, and they grew angry and “sought to lay hand on the king Ahasuerus.” Mordecai heard of the plot and told Esther, who passed it to the king in Mordecai’s name. When it was checked, it proved true and both men were hanged. The deed was recorded in the chronicles, and later, on a sleepless night, the king has it read to him. That reading, in Esther 6, begins Mordecai’s turn of fortune.
