'Authority' in the Bible

And let the king appoint officers throughout all the provinces of his kingdom to gather all the attractive young women to Susa the citadel, to the harem under the authority of Hegai, the king's eunuch who oversees the women, and let him provide whatever cosmetics they desire.

It so happened that when the king's edict and his law became known many young women were taken to Susa the citadel to be placed under the authority of Hegai. Esther also was taken to the royal palace to be under the authority of Hegai, who was overseeing the women.

In the evening she went, and in the morning she returned to a separate part of the harem, to the authority of Shaashgaz the king's eunuch who was overseeing the concubines. She would not go back to the king unless the king was pleased with her and she was requested by name.

So Queen Esther, the daughter of Abihail, and Mordecai the Jew wrote with full authority to confirm this second letter about Purim.

Now all the actions carried out under his authority and his great achievements, along with an exact statement concerning the greatness of Mordecai, whom the king promoted, are they not written in the Book of the Chronicles of the Kings of Media and Persia?
