'Seven' in the Bible

A week later, when the king was under the influence of all that wine, he ordered Mehuman, Biztha, Harbona, Bigtha, Abagtha, Zethar, and Carcas, the seven eunuchs who served King Ahasuerus,

(His closest advisors were: Carshena, Shethar, Admatha, Tarshish, Meres, Marsena, and Memucan, the seven officials of Persia and Media who had direct access to the king and who held the highest rank in the kingdom.)

The young woman pleased him and gained his favor. He quickly provided her beauty treatments and gave her portions of food to her. He also assigned her seven suitable young women from the palace and transferred her and her young women to the best place in the harem.
