ah, but they were. Abraham was an Amurru/Amorite and his wife Sarah was a Hittite. Both, are patriarchal Indo-European nations. Hebrew is a later designation for Habiru/Ibriy, which was an Akkadian term for the Amurru nomadic pastoral tribes that took over the territory known as Canaan, eventually spreading their empire as far as Babylon for a time.

Yechezqel [Ezekiel] 16:3, “And say, so says adonay YHWH to Yerushalem, the place of your origin and the place of your birth is of the land of the Kenaaniy [Canaanite]. Your father, the Amoriy [Amarru, Amorite] and your mother, Chiththiyth [female suffix with Hittite, basically Hittitess].” Canaan was originally called the land of the Amurru. The names of Abrahams family line are Amorite names.

Go back and read all the accounts in Bereshiyth/Genesis concerning Abraham and Sarah, notice that journey from Ur to Canaan is the same path as the Amurru empire. Harran was a major Amurru city. There was a confederacy between the Amorites and the Hittites, as evidenced by a treaty between the two nations, about 1230 BCE [The Hittites, J. G. Macqueen, 1986, pg. 40]. These good relations are apparent in the book of Bereshiyth [Genesis] in relation to Abraham, the father of the faith, who is an Amoriy. He marries Sarah, who according to the verse in Yechezqel mentioned above, is a Chiththiy [Hittite]. Abraham entered the land of Kenaan from Harran, and later settled in the territory of the Amurru / Amorites, and made an alliance with Mamre, Aner and Eshkol [Bereshiyth – Genesis 14:13] - Amurru. Chapter 14 Abraham is living near Mamre with the Amurru, whom they had a tribal alliance with. At the point that Sarah dies, they are living in Hittite territory, of which Sarah is. Abraham secures land from the Hittites, who state that Abraham is a mighty prince among them, and according to Amorite/Hittite treaty laws, he was, with a cave for burial. This becomes the family tomb [Ber. 23]. If these Amorites and Hittites were as vile as later biblical editors would have you to believe, then why was the “Father” of this faith “consorting with the enemy” and making covenants with them?
