'Eunuchs' in the Bible

On the seventh day, as King Ahasuerus was feeling the effects of the wine, he ordered Mehuman, Biztha, Harbona, Bigtha, Abagtha, Zethar, and Carcas, the seven eunuchs who attended him,

But Queen Vashti refused to come at the king's bidding conveyed through the eunuchs. Then the king became extremely angry, and his rage consumed him.

The king asked, "By law, what should be done to Queen Vashti in light of the fact that she has not obeyed the instructions of King Ahasuerus conveyed through the eunuchs?"

In those days while Mordecai was sitting at the king's gate, Bigthan and Teresh, two of the king's eunuchs who protected the entrance, became angry and plotted to assassinate King Ahasuerus.

When Esther's female attendants and her eunuchs came and informed her about Mordecai's behavior, the queen was overcome with anguish. Although she sent garments for Mordecai to put on so that he could remove his sackcloth, he would not accept them.

So Esther called for Hathach, one of the king's eunuchs who had been placed at her service, and instructed him to find out the cause and reason for Mordecai's behavior.

it was found written that Mordecai had disclosed that Bigthana and Teresh, two of the king's eunuchs who guarded the entrance, had plotted to assassinate King Ahasuerus.

While they were still speaking with him, the king's eunuchs arrived. They quickly brought Haman to the banquet that Esther had prepared.

Harbona, one of the king's eunuchs, said, "Indeed, there is the gallows that Haman made for Mordecai, who spoke out in the king's behalf. It stands near Haman's home and is seventy-five feet high." The king said, "Hang him on it!"
