'Eunuchs' 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,

Queen Vashti refused to come at the king's order that was brought by the eunuchs.

The king inquired, "According to law, what should be done to Queen Vashti because she did not obey the order of King Ahasuerus that was delivered by the eunuchs?"

At that time when Mordecai was sitting in the king's gate, Bigthan and Teresh, two of the king's eunuchs among those who guarded the threshold, became angry and conspired to assassinate King Ahasuerus.

When Esther's young women and her eunuchs came and told her, the queen was greatly distressed. She sent clothes for Mordecai to put on so he could take off the sackcloth that he had on, but he would not take them.

Then Esther summoned Hathach, one of the king's eunuchs, whom he had assigned to her, and she ordered him to go to Mordecai to find out what was happening and why it was happening.

It was found recorded there that Mordecai had reported about Bigthana and Teresh, two of the king's eunuchs who guarded the entrance to the restricted areas of the palace, and that they had conspired to assassinate King Ahasuerus.

While they were still talking to him, the king's eunuchs arrived, and they quickly took him to the banquet that Esther had prepared.

Then Harbonah, one of the eunuchs attending the king, observed, "Look there! A pole is standing 50 cubits high at Haman's house that he prepared for Mordecai, whose report benefitted the king!"
