Clearly you do Not know your Bible.Your question was answered to a far greater extent than just a simple Yes or No.Looks like he wants to avoid the question.
It was clear you avoided the questions. The questions were are Arabs still mad at the descendants of Jacob because esau sold his birth-right ?
The Bible explicitly says that the division between arabs an jews started with the two son's of Abraham; Isaac, father of the jews; and Ishmael, father of the arabs.
Plus, the O.T. gives a complete listing of both son's descendants and their tribes.
Thus, Jacob and Esau have absolutely ZERO to do with the arabs according to the Bible.
Man, I really dislike having to teach Christian's what their Bible says.
