Eunuch

From BibleWiki

Literally bed-keeper or chamberlain, and not necessarily in all cases one who was mutilated, although the practice of employing such mutilated persons in Oriental courts was common (2Kg 9:32; Est 2:3).

The law of Moses excluded them from the congregation (Deut 23:1). They were common also among the Greeks and Romans. It is said that even to-day there are some in Rome who are employed in singing soprano in the Sistine Chapel.

Three classes of eunuchs are mentioned in Mt 19:12.
