'Freeman' in the Bible

When thou buyest a Hebrew servant -- six years he doth serve, and in the seventh he goeth out as a freeman for nought;

'And when a man smiteth the eye of his man-servant, or the eye of his handmaid, and hath destroyed it, as a freeman he doth send him away for his eye;

and if a tooth of his man-servant or a tooth of his handmaid he knock out, as a freeman he doth send him away for his tooth.
