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 hand on the king Ahasuerus.12 22And the thing was known to Mordecai, who told it unto Esther the queen; and Esther certified the king thereof in Mordecai’s name. 23And when inquisition was made of the matter, it was found out; therefore they were both hanged on a tree: and it was written in the book of the chronicles before the king.
