Kibbutz Galuyot Supernaturally

In the haftara for the 8th day of Pesah for those outside of Israel (which, by the way, kind of makes sense to be read only by those outside of Israel), we read (Yeshaya 11:15-16):

וְהֶחֱרִים יְהוָה, אֵת לְשׁוֹן יָם-מִצְרַיִם, וְהֵנִיף יָדוֹ עַל-הַנָּהָר, בַּעְיָם רוּחוֹ; וְהִכָּהוּ לְשִׁבְעָה נְחָלִים, וְהִדְרִיךְ בַּנְּעָלִים

And the LORD will utterly destroy the tongue of the Egyptian sea; and with His scorching wind will He shake His hand over the River, and will smite it into seven streams, and cause men to march over dry-shod.

וְהָיְתָה מְסִלָּה--לִשְׁאָר עַמּוֹ, אֲשֶׁר יִשָּׁאֵר מֵאַשּׁוּר: כַּאֲשֶׁר הָיְתָה לְיִשְׂרָאֵל, בְּיוֹם עֲלֹתוֹ מֵאֶרֶץ מִצְרָיִם

And there shall be a highway for the remnant of His people, that shall remain from Assyria, like as there was for Israel in the day that he came up out of the land of Egypt.

3 years ago, I had a post called Keri'at Atlantic, where I wrote that it seems from the commentaries on Yeshaya 11:15-16 that there will be a dry path that will allow the Jews to pass from wherever they are to come to Eretz Yisrael during Kibbutz Galuyot.

The Sha'arei David on these verses says:

אף שאין נראה בימינו הכרח לעבור דוקא דרך ים מצרים כי עוד דרכים יש, מ״מ בזמן קיבוץ הגלויות יהיה גילוי שהוא קיבוץ בדוקא להביא את ישראל אל אדמתם ולא קיבוץ של הסכמת שרי עכו״ם או נדידת עמים, אלא הקב״ה מקבצם קיבוץ גאולה, וע״כ יש הוראה לזאת ע״י שנסללת עבורם הדרך שלא כדרך הטבע וכמו שהיה ביציאת מצרים, וזה שאמר בפםוק אח״ז והיתה מסלה לשאר עמו אשר ישאר מאשור כאשר היתה לישראל ביום עלתו מארץ מצרים, היינו שכל זה נעשה עבור שנראה מסילה לעמו ולא קיבוץ כבשאר עמים, וזה נאמר תלמוד לדידן שלא תסבור בקיבוצים אחרים או הסכמות עמים ונדידת סוחרים שזה קיבוץ גאולה, כי בגאולה יהיה נגלה שנסלל עבורם מסילה בדוקא גם בייבוש ימים וכבישת דרכים עבור עמו, נזכה במהרה (ועיין לקמן פרק מ״ט פסוק י״א).

Even though it doesn't appear in our days to be a necessity to travel specifically by way of the "Sea of Egypt" as there are other ways to travel, nevertheless, at the time of the ingathering of the exiles, it will be revealed that it is an ingathering specifically to bring Israel to their land and not an ingathering of non-Jewish officers' agreements or nations migrating. Rather, HKB"H gathers them as an Ingathering of Redemption. Therefore, there is an instruction for this by way of paving a path for them supernaturally - just like there was during the Exodus from Egypt. And that is what it says in the following verse, "And there shall be a highway for the remnant of His people, that shall remain from Assyria, like as there was for Israel in the day that he came up out of the land of Egypt." That means that all this was done in order to see a path for His nation - and not an ingathering like the rest of the nations... so you should not think that in other ingatherings or nation's agreements or migrations of merchants that these are Ingatherings of Redemption. This is because during the Redemption, it will be revealed that a pathway will be paved for them specifically - also with the drying up of seas and the capturing of roads for His people. We should merit this quickly. (See later 49:11.)

He refers you to Yeshaya 49:11, which reads:

וְשַׂמְתִּי כָל-הָרַי, לַדָּרֶךְ; וּמְסִלֹּתַי, יְרֻמוּן

And I will make all My mountains a way, and My highways shall be raised on high.

This seems to indicate an alternative way to get to Eretz Yisrael - via a "high"-way. An airplane, perhaps? No, as this would be too natural in our day. It seems that there will be something more supernatural that will bring us there.  Not that the current settlement in Eretz Yisrael is not miraculous.  It most definitely is.  However, if we are to compare our ingathering to the Exodus, there will be open miracles that will be clear to all.

As we say in the 10th blessing of the Amida:

תקע בשופר גדול לחירותינו ושא נס לקבץ גליותינו

Blow the Great Shofar for our freedom and lift a banner to ingather our exiles

Many commentaries (these sources are from Munkatch Hasidim, but I've heard this from other sources as well) say that ושא נס can also mean that it will happen supernaturally.
