For whereas there be two sorts of Servants; that
sort, which is of those that are absolutely in the power of their
Masters, as Slaves taken in war, and their Issue, whose bodies are not
in their own power, (their lives           on the Will of their Masters,
in such manner as to forfeit them upon the least disobedience,) and that
are bought and sold as Beasts, were called Douloi, that is properly,
Slaves, and their Service, Douleia: The other, which is of those that
serve (for hire, or in hope of benefit from their Masters) voluntarily;
are called Thetes; that is, Domestique Servants; to whose service the
Masters have no further right, than is contained in the Covenants made
betwixt them.
