From Adam, the rise of Homo Sapiens, to Avraham were 150 historical Idanim. From Avraham to Yetziat Mitzrayim were three historical Idanim, corresponding to Avraham, Yitzchak, and Ya'akov. From Yetziat Mitzrayim to Bayit Rishon was one historical Idan. From Bayit Rishon to Bayit Sheni were 10/3 historical Idanim, three and a third, a fulfillment of the prophecy of Daniel 7:25 that the repression of Israel is to be "until an Idan, Idanim, and a fraction of an Idan". At a deeper level, then, the book of Daniel hints that ten historical Idanim are from Yetziat Mitzrayim until death will completely loose its power.
Three Idanim is 1440 years, close to the Bond cycle length of plagues of climatic change and massive migrations of human populations. Yetziat Mitzrayim fits the scheme. Following Yetziat Mitzrayim was the Idan of the first prophets in the Land of Israel. Three Idanim later was the Idan of the later prophets in the Land of Israel. Yet three Idanim later, the exile would have ended (see Sanhedrin 97b), but the rise of Islam granted Ishmael his 1300 years of rule over the Land, according to the years of his Milah. Yet three Idanim later is now.
The Idan of Chochma was from the year -111 until the year 389, 500 years from the historical event that corresponds to Noach's flood, until the historical event that corresponds to the dispersion from Shinar. The historical flood was likely in the same area. Year -111 is 5880 years ago, the time of the 5.9 kiloyear event. There is scientific evidence for a great flood in Mesopotamia around this time which brought an abrupt end to the Ubaid period in Ur. The Middle East became an area of much drought.
Avraham came from Ur Kasdim, likely in Shinar, the center of idol worship. Avraham's soul is rooted in the Idan of Chochma, the Idan of Shinar - the sephira of Chesed is related to the sephira of Chochma. Note that Avraham, fleeing drought, moves to Mitzrayim, the second center of idol worship, and that he had to leave for the Land of Israel just like his father had to leave Ur Kasdim for Charan. Note that there were 500 years from the birth of Avraham to Yetziat Mitzrayim.
The Idan of Bina was from year 389 until year 789, 400 years from the dispersion from Shinar until when Terach took his family from Charan, the free land of shephards, across the river Prat, to Ur Kasdim, the city of oppression.
In Ur Kasdim, Charanites were called Ivri'im, the settlers across the river Prat. They were the Mitnachalim of their time. Yitzchak is the purest Ivri. He never left the Land of Israel, not even for Charan. The sephira of Gevura is related to Bina. Note that there were 400 years from the birth of Yitzchak to Yetziat Mitzrayim.
The Idan of Da'at was from year 789 until year 1329, 540 years from Terach's move to Ur Kasdim until Yisrael's leaving Mitzrayim as a nation. Tif'eret is related to Da'at, Ya'akov lived in a period that fitted his soul. From his birth until Yetziat Mitzrayim is 340 years - add twice 100 years for Avraham and Yitzchak. Ya'akov combines Yitzchak and Avraham. He took his family to Mitzrayim in year 1119, to return as a nation of Ivri'im. In Mitzrayim, the Old Kingdom arose in the wake of Yosef's reforms.
From 1329 until 1809 is 480 years, the Idan of the early prophets, from leaving Mitzrayim as a nation until Bayit Rishon and great worldly power.
From 1809 until 2929 is from Bayit Rishon to Eliyahu HaNavi, two Idanim and a third for the rise and the fall of the Hyksos - the return to Mitzrayim, as a nation. After all, it must be that Bnei Yisrael were 430 years in Egypt (Shemot 12:40).
From 2929 until 3409 is from Eliyahu HaNavi to Bayit Sheni, the Idan of the later prophets. The Ivri'im return, powerless, but vowing to stay a nation of Ivri'im forever.
What followed is history, the long and final exile, and Israel's definitive return from that exile.
