Did the plague of darkness cross the boundaries of Goshen?
Why is the plague of darkness the only one in which the Torah reveals that the opposite was happening to the Israelites?
Moshe lifted his hand towards the sky and there was obscuring darkness throughout the land of Egypt for three days. People could not see one another nor could anyone rise from beneath [the palpable, immobilizing darkness] for [another] three days. However, there was light for all of the Bnei Yisrael in their dwellings.
— Shemos 10:22,23
Arise, shine, for your light has come, and the glory of the HaShem shines upon you. For, behold, darkness covers the earth and dark thick clouds [covers] the peoples; but upon you HaShem will shine, and His glory will be seen upon you. Nations will walk by your light and kings [will march] by the radiance of your shine.
— Yeshaya 60:1-3
No longer will the sun provide you with daylight and radiance, nor will the moon illuminate [the night for you]; but HaShem will be an everlasting light for you, and your Elokim will be your brilliance.
— Yeshaya Ibid:19
Even the darkness is not too dark for You, but the night shines as the day; the darkness is as the light.
— Tehillim 139:12
HaShem will plague Egypt, plaguing and healing …
— Yeshaya 19:22
“Plaguing†the Egyptians and “healing†the Bnei Yisrael-the Children of Israel.
— Zohar commenting on the above pasuk
As in the days of your exodus from land of Egypt I will display miraculous things.
— Michah 7:15
Rabi Yehudah combined and split up the makkos-plagues of Egypt; into simanim– mnemonics: Dtzacâ€h, Adasâ€h, B’achaâ€v
— Haggadah shel Pesach
The Midrash says that wherever a Jew would sit down things would become illuminated for him. Rav Leibeleh Eiger explains that the Midrash deduces this from the difference in the Torahs description of the Bnei Yisrael being unaffected by makkas choshech– the plague of darkness; compared to the makkas barad-plague and hail. When describing the plague of hail the Torah writes: “It was only in the Goshen where Bnei Yisrael were, that there was no barad†(Shemos 9:26). If makkas choshech had been identical to makkas barad what we should have had was a pasuk reading something along the lines of “No darkness dimmed the land of Goshen†or “there was abundant light throughout the boundaries of the Bnei Yisrael.†Instead the pasuk emphasizes the dwellings of the Bnei Yisrael rather than a particular area on the map of Egypt.
In fact, darkness lay on the land uniformly and respected no boundaries. Darkness fell into pharaoh’s palace and land of Goshen equally. The dichotomy between the Egyptian and the Israelite experience during this plague was not geographically rooted. Instead, it derived from the difference between the Israelite an Egyptian soul. As the Jewish soul cleaves to HaShem, the dynamic that allowed the Bnei Yisrael to be untouched by this plague was that the Ohr Ein Sof Baruch Hu-the Light of the Endless One – Blessed is He [alternatively the Endless Light– Blessed is He]; was with them and, perhaps, diffusing through them.
While we’re all very familiar with the simanim of the Haggadah: Dtzacâ€h, Adasâ€h, B’achaâ€v , dividing the 10 plagues of Egypt into two sets of three followed by a final set of four, Rav Leibeleh Eiger introduces another way of categorizing the plagues. He asserts that only during the first nine of the plagues, of which darkness is the final one, did the Egyptians have the opportunity of exercising their free will to liberate the Bnei Yisrael and dismiss them from the land. The final plague, makkas bechoros-the smiting of the firstborn; forced their hands. At that point they had they no longer had any choice in the matter. Viewed in this way the makkos are divided into 9+1. Makkas chosech was the final plague while makkas bechoros was something qualitatively different altogether. As such, makkas chosech was the beginning of geulah-redemption; of the Bnei Yisrael from the Egyptian exile.  As darkness engulfed the land the salvation began.
In Jewish eschatology one of the hallmarks of the ultimate Geulah at the end-of-days, is that the presence of G-d will be palpable and manifest and that all powerless idols and false ideologies will be exposed for the obscuring mirages they are. Their smoke —their pollution — will blow away, scattered by the fresh winds of truth. The Geulah will be a kind of cosmic reboot where everything is reset and recalibrated to the Manufacturer’s factory settings. In order to get a glimpse of the ultimate Geulah it is instructive to study the sources describing how these “factory settings†where first fiddled with and misaligned.
