By all the strong hand, see, the faithful shepherd comes, and starts to speak: Rabbi, rabbi, Yisrael certainly stands against several challenges in the Galut, and they gave themselves over to death. And come and see, the Sin of Adam caused death to exist in the world. But the Sin of Kain caused how many Tzaddikim from Yisrael to be killed at the hands of the nations, idol worshippers. But, come and see, Kain himself, what caused him to sin? It was because his sacrifice was not clean, and thus is written: Because of this, he got more corrupted, and the Sitra Achra became stronger on him, and he killed Chevel.
At the same time, the left arm became impaired by him, surely, as Kain was dependent on that arm. Because that impaired arm, they had to die. And the secret of the matter: Who die at your hand, Hashem (Tehilim 17:14), that is the left hand, which got impaired. After all, because of this hand, many from Yisrael had to die.
[Gog is the master of antisemitism. Kain killed his brother; the first Mashal of antisemitism. The first time that Gog came to the gate of Yerushalayim, he killed many, but not Moshiach ben Yosef in Zion, who will defeat Gog in the end; see also the Mashal of the waters of Noach.]
And the secret of the matter: Who is clean by way of his mother, he goes up {Chagiga 15b}. Hence is the secret: Who wants to go up one level higher, when he is not clean, he surely gets more corrupted. This is what happened to Elisha, the "other" (Chagiga 14b,15). And this is the secret: Every word of God is refined {Mishlei 30:5}. Who merits, his jewels will be towards life; who does not merit, his jewels will be towards death.
In the future, Kain will become clean. In those days, I will clean their blood, which I did not clean (Yoel 4:21). They are who are murdered by the nations, which will all return to their place, and the above arm will receive a proper Tikkun, and that is the strong hand. By all the awesome power - that is Moshiach ben Yosef, because he is invited to achieve this Tikkun, in its entirety.
[Therefore, Moshiach ben Yosef still has a crucial task to do, to destroy the baseless hatred of the other, in the human heart, which is the base of antisemitism, and then to defeat Gog.]
