Abraham had two sons the eldest Ismael by his slave girl.
It was Ismael who was the founder of the Arab nations and in AD 600 the birth of Islam.
Abrahams second son was Isaac by his wife who had been sterile but gave birth to Isaac when she was about 70.
It was Isaac who founded the tribes of Israel which in turn produced Judism . Which in turn produced Jesus Christ and Christianity.
That is why both Arabs and Jews claim thir ancient right to the land of Israel.
However there is no positive proof that Abram ( His first name ) ever existed.
This is only a potted history but I hope it helps.
They remind me of the rioters in this country. Take or steal what you can get and bother about the consequences. There will never be peace in Israel until they treat the Arabs equally as they do their own citizens.
Why don't they reserve half the flats for the Arabs if they really want peace?
