I have been reading the following from J J Prasch. In this article he explains the dissidents between two generations of brothers found in the Old Testament.
This envy and everlasting hatred will play out the way God said it would.
To find out what happens next you have to read the article…
The Psalmist, being a prophet, agrees with the other Hebrew prophets about the reasons for this hostility of Edom towards his brother Israel. Ezekiel calls it “everlasting hatred” …
“Moreover the Word of the Lord came to me saying, Son of man, set your face against Mt Seir (Edom) and prophesy against it, saying to it, Thus says the Lord God: ‘Behold O mount Seir, I am against you, and make you a desolation and a waste; I shall lay your cities waste, and you shall be desolate. Then you shall know that I am the Lord. Because You have had an everlasting hatred and have shed the blood of the children of Israel by the power of the sword at the time of their calamity when their iniquity came to an end.” (Ezekiel 35:1-5)
This “everlasting hatred” is currently embodied in Islam but is older than Islam. It goes back to Ishmael, Abraham’s eldest son, who was disenfranchised of his inheritance (in his own and his mother Hagar’s mind) by the birth and election of Isaac. “In Isaac shall thy seed be called…”. Far from a mere Sunday school lesson, this division between the child of the handmaid and the chosen seed of Abraham is directly relevant to at least a third of everyone now living!
Muslims (one out of seven people in the world) believe that Ishmael was the chosen seed of Abraham, and celebrate the feast of EID to commemorate their version of the Abraham story, the sacrifice of Ishmael. As Ishmael was supposedly disenfranchised by Sarai and Abraham, being evicted from Abraham’s tent, so the Arab Muslim world nurtures that same sense of resentful disenfranchisement, focusing their resentment on Jews and Christians.[source]
