Esther 2:19-23

19 Meanwhile Mordecai had been appointed by the king to an administrative position.
20 As for Esther, she had still not let it be known that she was Jewish. Mordecai had told her not to tell anyone, and she obeyed him in this, just as she had obeyed him when she was a little girl under his care.
21 During the time that Mordecai held office in the palace, Bigthana and Teresh, two of the palace eunuchs who guarded the entrance to the king's rooms, became hostile to King Xerxes and plotted to assassinate him.
22 Mordecai learned about it and told Queen Esther, who then told the king what Mordecai had found out.
23 There was an investigation, and it was discovered that the report was true, so both men were hanged on the gallows. The king ordered an account of this to be written down in the official records of the empire.
