Esther 1:13-14

13Then the king spoke to the wise men who understood the times [asking for their advice]—for it was the custom of the king to speak before all those who were familiar with law and legal matters—

14and who were close to him [as advisors]: Carshena, Shethar, Admatha, Tarshish, Meres, Marsena, and Memucan, the seven officials of Persia and Media who had access to the king and were ranked highest in the kingdom.
