'Servant' in the Bible

Let the king give authority to certain men in all the divisions of his kingdom, to get together all the fair young virgins and send them to Shushan, the king's town, to the women's house, under the care of Hegai, the king's servant, the keeper of the women: and let the things needed for making them clean be given to them;

And he was pleased with the girl and was kind to her; and he quickly gave her what was needed for making her clean, and the things which were hers by right, and seven servant-girls who were to be hers from the king's house: and he had her and her servant-girls moved to the best place in the women's part of the house.

Now when the time came for Esther, the daughter of Abihail, his father's brother, whom Mordecai had taken as his daughter, to go in to the king, she made request for nothing but what Hegai, the king's servant and keeper of the women, had given her. And Esther was looked on kindly by all who saw her.
