Esther 6:1-2

On that night the king could not sleep; so he ordered that the book of records and memorable deeds, the chronicles, be brought, and they were read before the king. It was found written there how Mordecai had reported that Bigthana and Teresh, two of the king’s eunuchs who were doorkeepers, had planned to attack King Ahasuerus (Xerxes).
