'Maid servant' in the Bible

That every man should let his manservant, and every man his maidservant, being an Hebrew or an Hebrewess, go free; that none should serve himself of them, to wit, of a Jew his brother.

Now when all the princes, and all the people, which had entered into the covenant, heard that every one should let his manservant, and every one his maidservant, go free, that none should serve themselves of them any more, then they obeyed, and let them go.

And -- ye turn back, and pollute My name, and ye cause each his man-servant and each his maid-servant, whom he had sent forth free, (at their pleasure,) to return, and ye subdue them to be to you for men-servants and for maid-servants.
