My choice of words, not the Bible's. Which is why I didn't put it in quotes.
What Ishmael is is the product of Abraham's lack of faith in God's word. God promised him many descendants. As Sarah advanced in age with no children, Abraham panicked ("O Lord God, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?). It was a test of his faith, which he failed.
Ishmael, father of the Arabs, was the product of that failure.
The Koran was simply a rewrite of this history for the sole purpose of elevating the bastard (again, my word) Ishmael's status.
“Ishmael, father of the Arabs, was the product of that failure.”
Another possibility, perhaps, of Cho’s alliance with Ishmael as the outcast:
Genesis 16:12 “He shall be a wild ass of a man, his hand against everyone, and everyone’s hand against him; In opposition to all his kin shall he encamp.”
...and we are still paying the price for Abe’s lack of faith in God’s spoken Word.
