'Eunuch' in the Bible

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

Now when Ebed-melech 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,)

And he arose and went: and behold, 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;

And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other?

And as they went on the way, they came unto a certain water; and the eunuch saith, Behold, here is water; what doth hinder me to be baptized?

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

And when they came up out of the water, the Spirit of the Lord caught away Philip; and the eunuch saw him no more, for he went on his way rejoicing.
