'Unsexed' in the Bible

(After Jeconiah the king and the queen-mother and the unsexed servants and the rulers of Judah and Jerusalem and the expert workmen and the metal-workers had gone away from Jerusalem;)

The rulers of Judah and the rulers of Jerusalem, the unsexed servants and the priests and all the people of the land who went between the parts of the ox,

Now it came to the ears of Ebed-melech the Ethiopian, an unsexed servant in the king's house, that they had put Jeremiah into the water-hole; the king at that time being seated in the doorway of Benjamin:

Then Johanan, the son of Kareah, and all the captains of the forces who were with him, took all the rest of the people whom Ishmael, the son of Nethaniah, had made prisoners, after he had put to death Gedaliah, the son of Ahikam, the people from Mizpah, that is, the men of war and the women and the children and the unsexed servants, whom he had taken back with him from Gibeon:

And from the town he took the unsexed servant who was over the men of war, and seven of the king's near friends who were in the town, and the scribe of the captain of the army, who was responsible for getting the people of the land together in military order, and sixty men of the people of the land who were in the town.
