We Jews refer to ourselves as either yehudi or bnei yisrael. Our language Hebrew we call ivrit, which roughly translates to "from over there", being a nod to our Mesopotamian origins across the Jordan River. Think Abraham who came from Ur Kasdim.
The word Hebrew itself is a Greek word changed via Latin.
