'Eunuch' in the Bible

Let the king appoint officers in all the provinces of his kingdom, that they may gather together all the beautiful young virgins to the citadel of Susa, to the women's house, to the custody of Hegai the king's eunuch, keeper of the women. Let cosmetics be given them;

In the evening she went, and on the next day she returned into the second women's house, to the custody of Shaashgaz, the king's eunuch, who kept the concubines. She came in to the king no more, unless the king delighted in her, and she was called by name.

Now when the turn of Esther, the daughter of Abihail the uncle of Mordecai, who had taken her for his daughter, came to go in to the king, she required nothing but what Hegai the king's eunuch, the keeper of the women, advised. Esther obtained favor in the sight of all those who looked at her.

Neither let the foreigner, who has joined himself to Yahweh, speak, saying, "Yahweh will surely separate me from his people;" neither let the eunuch say, "Behold, I am a dry tree."

Now when Ebedmelech the Ethiopian, a eunuch, who was in the king's house, heard that they had put Jeremiah in the dungeon (the king then sitting in the gate of Benjamin),

He arose and went; and behold, there was a man of Ethiopia, a eunuch of great authority under Candace, queen of the Ethiopians, who was over all her treasure, who had come to Jerusalem to worship.

The eunuch answered Philip, "Who is the prophet talking about? About himself, or about someone else?"

As they went on the way, they came to some water, and the eunuch said, "Behold, here is water. What is keeping me from being baptized?"

He commanded the chariot to stand still, and they both went down into the water, both Philip and the eunuch, and he baptized him.

When they came up out of the water, the Spirit of the Lord caught Philip away, and the eunuch didn't see him any more, for he went on his way rejoicing.
