When Yosef was sold to Mitzrayim, Yaakov had been learning with him the Parsha of Egla Arufa. We can suggest that Egla Arufa was the counterpoison for Galus Mitzrayim. The true great people are those who struggle and fall again and again; yet they continue to work on themselves, and daven for Yeshuos in Ruchaniyus.
Egla Arufa comes for the tragedy of taking away a person’s ability to “produce”, which is exactly the failure of Mitzrayim, a place of: שְׁתוּפֵי זִימָה immorality. Immorality is called: הַשחָתָה destruction, and is the opposite of normal P'ru uR'vu (producing). And Yosef was being sold to the Nisayon of the wife of Potiphar.
Mitzrayim’s whole name means: מֵצַר restriction, boundary, and lack of productivity, since P'ru uR'vu means nothing to a Mitzri; all he cares about is his lusts. The greatness of Yosef was his being Davka extreme in productivity; and he ended up saving the entire world from starvation. Indeed, conquering vain Hevel Ta'avos is synonymous with being productive.
Like the Rambam says that the true way to conquer Ta'avos is to fill your head up with Torah (and: תּוֹמֵחַ לוֹמוֹשֵׁל fighting in learning) which is A-1 productivity (especially Chidushei Torah) since learning Torah holds up the entire world. Notice how as soon as the Yidden came to Mitzrayim, they were extreme in P'ru uR'vu, with six at a time. And for good reason: וַיָּקֻצוּ מִפְּנֵי בְּנֵי יִשְׂרָאֵל the Mitzri'im were disgusted with the Bnei Yisroel; a Mitzri hates productivity!
That was a message from Shamayim to be different than a Mitzri, and Davka go extreme and have lots of children. This is a great Pshat that explains why we needed to multiply in Mitzrayim to the extreme. And of course, בִּזְכוּת נָשִׁים צְנוּעוֹת נִגְאֲלוּ we were redeemed from Mitzrayim in the Zechus of the Tzniyus'dike women. We were the opposite of: הַשחָתָה destruction.
We mentioned that our going to war is always an Inyan of building a house and producing. It is interesting that when Shlomo HaMelech talked about davening towards the Bais Hamikdash, he speaks about a soldier facing Bais (the “house” of) Hashem!
