Hebrew refers to the descendents of Abrahams son Israel, while Jews refers to the descendents of Abrahams grandson Judah.
So Abraham was born in Ur of Chaldees and could not have been a Jew. Firstly, Ur of Chaldees was in Mesopotamia, which is now a part of Iraq. He was then more an Arab than a Jew.
To summarize: Abraham was a Hebrew. The descendants of Jacob were Israelites consisting of the twelve tribes. Judah was
nicknamed Jew so that only Judahs descendants were called Jews originally . So Moses was not a Jew because he was not descended from Judah but a Levite, To know who Moses really was, read Exodus 6:16-20
Qur'an 2:140
Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allah ?" And who is more unjust than one who conceals a testimony he has from Allah ? And Allah is not unaware of what you do.
Quran 2:6 Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.
