1) "The J1e... have been estimated as descending from most recent common ancestors living 3,200"...
2) J2a possible Cohen clusters.... have been estimated as descending from most recent common ancestors living 4,200"....
You've left off data.
"± 1,300" means that there is an estimated range of 5,500 years ago to 2,900 years ago.
That doesn't support your claim of an exact 1360 BC date. It means that the closest ancestors related to all these men could have begun in 900 BC or in 3,500 BC or anywhere in between. That does not support your claim.
3) More recent research, using a larger number of Y-STR markers to gain higher resolution more specific genetic signatures,
has indicated that about half of contemporary Jewish Kohanim share Y-chromosomal
haplogroup J1c3...
Don't think I do not notice that you've altered the quote.
It says "about half of contemporary Jewish Kohanim,
who share Y-chromosomal
haplogroup J1c3 (also called J-P58), do indeed appear to be
very closely related.
What this means is that there are Kohanim who do not have that marker. If all Kohanim are directly from the same father, they should all share this halpotype. They do not.
However, haplogroup J1c3 IS shared by North Africans and found throughout the Arabian Peninsula. Why?
"
Chiaroni et al. (2010) propose that J1c3 (which they refer to as J1e) might have first dispersed during the
Pre-Pottery Neolithic B period, "from a geographical zone, including northeast Syria, northern Iraq and eastern Turkey toward Mediterranean Anatolia, Ismaili from southern Syria, Jordan, Palestine and northern Egypt".
Because the marker has existed since the Neolithic Period.
4) Recent mtDNA testing also confirms that these Jews in general are all related to just the four mothers described in Genesis, Leah, Rachael, Belhah, Zilpah:
Maternal line from 4 women

You obviously did not read this paper. The paper in not about "Jews, in general" but a specific group of Ashkenazi Jews. The research stipulates nothing regarding any persons appearing in the bible and can also exclude those persons you mentioned.
"It is noteworthy that our extensive sample set from
the Caucasus (table 5) does not offer any hint that the
four dominant Ashkenazi mtDNA lineages might have
arrived from this region. However, it can be concluded
that, irrespective of where exactly the mutations defining
these Ashkenazi lineages arose, their expansion clearly
took place during the time period of the sojourn of the
Ashkenazi population in Europe."
That doesn't even remotely describe Leah, Rachael, Belhah, or Zilpah.
Not to mention that Leah and Rachel are sisters so their lineage converges at their mother, meaning those would be three lineages, not 4.
Also, since ALL their children came from the same father, those four lineages should converge at the same place. They don't.
and are close to the (present) historical founding period of the Ashkenazi population, (i.e. European Jews).
