'Seven' in the Bible

On the seventh day, when the king was feeling good from the wine, Ahasuerus commanded Mehuman, Biztha, Harbona, Bigtha, Abagtha, Zethar, and Carkas, the seven eunuchs who personally served him,

The most trusted ones were Carshena, Shethar, Admatha, Tarshish, Meres, Marsena, and Memucan. They were the seven officials of Persia and Media who had personal access to the king and occupied the highest positions in the kingdom.

The young woman pleased him and gained his favor so that he accelerated the process of the beauty treatments and the special diet that she received. He assigned seven hand-picked female servants to her from the palace and transferred her and her servants to the harem’s best quarters.
