Ahdut Before Ge'ula
I've mentioned this idea before, but it bears repeating.
The entire sefer Bereishit deals with infighting between brothers. It begins with Kayin against Hevel, Ham against Shem and Yafet, Yishmael against Yitzhak, Eisav against Yaakov, and finally, the brothers against Yosef.
As the verse says הנה מה טוב ומה נעים שבת אחים גם יחד. Why does it say "גם יחד"? This teaches you that it's a חידוש when brothers show togetherness.
Finally, in Vayigash, the brothers and Yosef make up with each other. But even more so, in Vayehi, we find 2 brothers that had no problems with each other at all - Ephraim and Menashe. Menashe was not jealous of Ephraim for getting the right-hand of Yaakov Avinu. This is why we bless our children with the verse that Yaakov Avinu uses: ישמך אלקים כאפרים וכמנשה.
And notice what comes right after he blesses Ephraim and Menashe:
ויקרא יעקב אל בניו ויאמר האספו ואגידה לכם את אשר יקרא אתכם באחרית הימים
He starts to want to talk about the End of Days.
The Ahdut of Ephraim and Menashe is the Ahdut we need during the time before the Final Redemption.
(See this video by R' Chaim Richman which also mentions this same concept.)
Notice that Akiva posted on how the whole of Israel is coming together during the war:
Radio stations, secular radio stations (!!!), are saying tehillim (psalms) on the air. Holy congregations are praying for the soldiers welfare and success. Chesed organizations (charities) have swung into action - preparing care packages for soldiers, preparing relief options for shell shocked southern residents under constant bombardment. Internal divisions have fallen away, all are taking steps to support and prepare.
Israel is standing together. Nervous, expectant, together. We may bicker and pick at each other. But like a family, it's all in the family and when in trouble we stand together.
May this Ahdut continue so that we may merit the Final Redemption.
