'Eunuchs' 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,
But Queen Vashti refused to come at the king’s command that was delivered by his eunuchs. The king became furious and his anger burned within him.
The king asked, “According to the law, what should be done with Queen Vashti, since she refused to obey King Ahasuerus’s command that was delivered by the eunuchs?”
During those days while Mordecai was sitting at the King’s Gate, Bigthan and Teresh, two eunuchs who guarded the king’s entrance, became infuriated and planned to assassinate King Ahasuerus.
Esther’s female servants and her eunuchs came and reported the news to her, and the queen was overcome with fear. She sent clothes for Mordecai to wear so he could take off his sackcloth, but he did not accept them.
Esther summoned Hathach, one of the king’s eunuchs assigned to her, and dispatched him to Mordecai to learn what he was doing and why.
They found the written report of how Mordecai had informed on Bigthana and Teresh, two eunuchs who guarded the king’s entrance, when they planned to assassinate King Ahasuerus.
While they were still speaking with him, the eunuchs of the king arrived and rushed Haman to the banquet Esther had prepared.
