Esther 2:3-4; Esther 2:9; Esther 2:21-23
You can appoint officials in every province of the empire and have them bring all these beautiful young women to your harem here in Susa, the capital city. Put them in the care of Hegai, the eunuch who is in charge of your women, and let them be given a beauty treatment.
Then take the young woman you like best and make her queen in Vashti's place." The king thought this was good advice, so he followed it.
Hegai liked Esther, and she won his favor. He lost no time in beginning her beauty treatment of massage and special diet. He gave her the best place in the harem and assigned seven young women specially chosen from the royal palace to serve her.
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.
Mordecai learned about it and told Queen Esther, who then told the king what Mordecai had found out.
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.
