Esther 2:19-23

Now when the virgins were gathered together the second time, Mordecai was sitting at the king’s gate. Esther had not made known her kindred or her people, as Mordecai had commanded her, for Esther obeyed Mordecai just as when she was brought up by him. In those days, as Mordecai was sitting at the king’s gate, Bigthan and Teresh, two of the king’s eunuchs, who guarded the threshold, became angry and sought to lay hands on King Ahasuerus. And this came to the knowledge of Mordecai, and he told it to Queen Esther, and Esther told the king in the name of Mordecai. When the affair was investigated and found to be so, the men were both hanged on the gallows. And it was recorded in the book of the chronicles in the presence of the king.
