'Eunuchs' in the Bible

the officials of Judah, and the officials of Jerusalem, the eunuchs, and the priests, and all the people of the land who passed between the parts of the calf--

Then Johanan the son of Kareah and all the commanders of the armies who [were] with him took from Mizpah all the rest of the people whom he had recovered from Ishmael the son of Nethaniah, after he had killed Gedaliah the son of Ahikam, strong men, {soldiers}, and women, and little children, and eunuchs whom he brought back from Gibeon.
