'Servant girl' in the Bible

That every man was to let his Hebrew man-servant and his Hebrew servant-girl go free; so that no one might make use of a Jew, his countryman, as a servant:

And this was done by all the rulers and the people who had taken part in the agreement, and every one let his man-servant and his servant-girl go free, not to be used as servants any longer; they did so, and let them go.

But again you have put shame on my name, and you have taken back, every one his man-servant and his servant-girl, whom you had sent away free, and you have put them under the yoke again to be your servants and servant-girls.
