What was biblical Abraham's race?

Answer 1

Abraham, or Abram, was the first Hebrew, but was originally a Chaldean (Genesis 11:31) from where we know of as Iraq. He is the father of both the Israelis and Arabs. He was of the human race.

Jewish answer:

Abraham, tenth generation descendant of Noah, of Hebrew lineage, was the son of Terah, uncle of Lot, father of Isaac, grandfather of Jacob, and ancestor of the Israelites. His story is in Genesis ch.11 (end), through ch.25. Jewish tradition states that he was the first to teach belief in One God.

Abraham is called a Hebrew (Genesis ch.14) because Hebrew (Ivrim) means descendants of Eber (Ever). Ever was an anscestor of Abraham (Genesis ch.10-11) and the early Hebrews were Abraham's uncles and cousins for several generations back. They were Western Semites (descendants of Shem, in Genesis ch.10-11) and lived in northern Mesopotamia, near the confluence of the Balikh and the Euphrates.

Nimrod, the idolatrous tyrant, had brought Abraham's father (Terah) from the Semitic ancestral seat near the conjunction of the Balikh and the Euphrates, and instated him in a position of power in his army in the royal Babylonian city of Ur, where Abraham was born.
