Esther 2:21-23

21One day, Mordecai was sitting at the king's gate. While he was there, two of the king's eunuchs, Bigthana and Teresh, became angry with King Xerxes. They decided that they would kill the king.

22Mordecai heard about this. So he told Queen Esther about it. Queen Esther told the king what Mordecai had said.

23The king sent his men to see if it was true. When he discovered that Mordecai had told the truth, he said that the two eunuchs must die. So his officers hanged them from a wooden tower until they were dead. They wrote about this event in the history book, while the king watched.
