The Madianites sold Joseph in Egypt to Putiphar, an eunuch of Pharaoh, captain of the soldiers.

And Joseph was brought into Egypt, and Putiphar, an eunuch of Pharaoh, chief captain of the army, an Egyptian, bought him of the Ismaelites, by whom he was brought.

After this, it came to pass, that two eunuchs, the butler and the baker of the king of Egypt, offended their lord.

Eunuchs are castrated male slaves.
