'Eunuch' in the Bible

And the Medanites have sold him unto Egypt, to Potiphar, a eunuch of Pharaoh, head of the executioners.

And Joseph hath been brought down to Egypt, and Potiphar, a eunuch of Pharaoh, head of the executioners, an Egyptian man, buyeth him out of the hands of the Ishmaelites who have brought him thither.
