Israel Today has reported numerous times regarding Christian Palestinians who claim to be the true Israel. In their case, the Palestinian Jesus is just an adaptation of the Arian-looking Jesus of the classic Christian iconography.
Likewise, reclaiming the Hebrew Bible for the Muslim/Palestinian cause is nothing new. From its get go, Islam had its followers believe that Jews corrupted the Old Testament to the point of rendering it unholy. Hence, whatever's written in the Hebrew Bible can be retold in a way that fits Islam's creeds.
It is well known that in the eyes of Muslims, all the prophets of the Bible were Muslims. That Islam came into being some 3,000 years after Abraham makes no difference since, unlike the Jews, Abraham is forever a true believer – a Muslim.
But even this Islamic version of "Replacement Theology" has its limits. For even Muslims will acknowledge that a real entity called the people of Israel not only exists, but to them the Land of Israel was given: "O my people [Israel]," reads the Quran, "enter the Holy Land which Allah has assigned to you and do not turn back and become losers" (Sura 5:21).
So the Palestinian reimagining of the Bible is going a step further. It wasn't Jews who came out of Egypt as the "people of Israel," but rather Muslims. Back in 2012, Dr. Omar Ja'ara of Nablus' An-Najah University told Palestinian TV:
"We must make clear to the world that David in the Hebrew Bible is not connected to David in the Quran, Solomon in the Hebrew Bible is not connected to Solomon in the Quran, and neither is Saul or Joshua son of Nun [of the Bible].
"We have a great leader, Saul, [in the Quran] who defeated the nation of giants and killed Goliath. This is a great Muslim victory. The Muslims of the Children of Israel went out of Egypt under the leadership of Moses, and unfortunately, many researchers deny the Exodus of those oppressed people who were liberated by a great leader, like Moses the Muslim, the believing leader, the great Muslim, who was succeeded by Saul, the leader of these Muslims in liberating Palestine.
"This was the first Palestinian liberation through armed struggle to liberate Palestine from the nation of giants led by Goliath. This is our logic and this is our culture."
(Translation from Palestinian Media Watch)
Those amused by this ridiculous revisionism forget that Muslims take it very seriously, and act upon it.
