The Hebrews became slaves in blank:
The Hebrew is the term used for the ancient people who came from what now is called Israel and Palestine. The Israelites are in Egypt for a very long time but they are working as servants for the pharaoh.
But the pharaohs feared the one day the large population of Israelites would turn against and would force pharaohs to become slaves, and that is why the Hebrews became slaves in blank, means even due to their large population the pharaohs are scared but still they are working as servants and that is why the Hebrews are slaves in blank.
