Esther 2:21-23

21In those days, while Mordecai sat in the king’s gate, two of the king’s chamberlains, Bigthan and Teresh, of those which kept the door, were wroth, and sought to lay hands on the king Ahasuerus. 22And the thing was known to Mordecai, who shewed it unto Esther the queen; and Esther told the king thereof in Mordecai’s name. 23And when inquisition was made of the matter, and it was found to be so, they were both hanged on a tree: and it was written in the book of the chronicles before the king.
