''So judiasm and the land of Judea was established in Abram's time.''That's not what I said, Sunshine, and you know it. It should be clear that I was referring to the history of Judaism and its tribes, Mosaic Law, Hebrews Israelites, factions, sects.....
Wake up, Noddy.
Just briefly;
The following is a brief overview of the history of Judaism:
ABRAHAM: FATHER OF MONOTHEISM:
Abraham was born in 1812 BCE in the city of Ur in Ancient Mesopotamia. According to Jewish tradition, he spent the first 40 years of his life questioning the polytheistic ideas of the surrounding culture, eventually coming to the conclusion that all of existence comes from a single source – a primal infinite Being that we call God. Once he was confident in the truth of his theory, he began to publicize his ideas through writing, teaching and public debates, and eventually built a movement of tens of thousands of people committed to a belief in one Creator and the philosophical principles which are an outgrowth of that belief. G-d then appears to Abraham for the first time and tells him that his biological descendants will eventually grow into a nation which will live by the philosophical principles that he had developed and will be given the Land of Canaan as a national homeland (Genesis 12:1).
A NATIONAL HOMELAND: 1200 YEARSIn 1272 BCE, after 40 years of traveling in the Sinai Desert, the Israelite Army, led by Joshua, conquers the Land of Canaan and inaugurates a period of over 1200 years of National experience in the Land of Israel, focused around the Jewish Temple in Jerusalem which existed for approximately 800 of those years (combining the 1st and 2nd Temple periods).
EXILE AND RETURN:
In 70 CE the Roman army destroys the Second Temple (the first was destroyed by the Babylonians about 500 years earlier) and from this point onwards, the majority of Jews live in various communities outside the Land of Israel. For the next 1900 years, the Jews in exile pray 3 times daily to be able to return to their homeland and in 1948 the dream is realized with a majority vote in the United Nations to allow the re-establishment of a Jewish State in the Land of Israel.
