, to save, which I leave to grammarians to dispute, is not meant a captive, which is kept in prison or bonds, till the owner of him that took him, or bought him of one that did, shall consider what to do with him: for such men, commonly called slaves, have no obligation at all; but may break their bonds or the prison; and kill, or carry away captive their master, justly: but one, that being taken, hath corporal liberty allowed him; and upon promise not to run away, nor to do violence to his master, is trusted by him.
