Tribes that have given trouble to Israel
Edomites (Esau, Gen. 36:9)
Ammonites (Amman, Jordan Gen. 19:38)
Moabites (Gen. 19:37)
Ishmaelites (Gen 16:11; 17:20)
Midianites (Same as Ishmaelites - Gen.37:28)

NOTE: All of these tribes settled in what is NOW Iraq, Jordan, Syria, Lebanon, Saudi Arabia, Kuwait
NOTE: Garden of Eden was in what is now Iraq. Abraham came from the location that is now Bagdad, Iraq. It was known as Babylon in two different periods of O. T. history.
NOTE: Think about all that is included in the term, "The God of Abraham, Isaac and Jacob." It would include all of these tribes. Today, some call Him "Jehovah" while others call His "Allah." All have their religious roots in Abraham, Isaac and Jacob.
