 It often was more a form of indentured labour.Ancient legal systems, included those of the Israelites seen in the Hebrew Bible, also typically distinguished between "native" and foreign slaves, with much better protection for the former.This distinction was transferred to Christian versus non-Christian slaves, sometimes with a component of "origin" as well, for example in Anglo-Saxon laws, but remained very important in Christian thinking and legal systems, in particular for the making of new slaves.
