Look how a Yid has to be Moser Nefesh (and not take N'kama) for the concept of: אַ חְ וָ ה brotherhood! In general, a Yid has to look at all other Yidden as a friend, as it says: וְאָהַבְתָ לְרֵּעֲךָ כָמוךָ קדושים יט יח Love your friend as you love yourself. All the Pesukim in Parshas Mishpatim that speak about Bain Adam La'chaveiro are all: רֵּ עִ ים friends, like: כִי יִתֵּן אִיש אֶּל רֵּעֵּהוּ כֶּסֶּף או כֵּלִים כב ו if someone will give his “friend” money or items, etc., i.e., we are all friends. It is interesting that: לֹא תִשְנָא אֶּת אָחִיךָ בִלְבָבֶּךָ קדושים יט יז You shall not hate your “brother” is an exception; hopefully the reminder that your friend is also a brother will stop a person from Sin'as Chinam (hatred) and promote Ahava (love).
All the Gedolim are saying that these days we have to work especially on Sin'as Chinam to bring the Geula, B’mheira B’yameinu, Amen, and being reminded that we are all brothers can be quite helpful. Especially the different Shitos (sects) can be major tests, since we can be so different than each other; and remembering we are brothers can be rather effective.
There was a Hamas Arab who became a Ger Tzedek, and he described how his own father treated him. When he misbehaved, his father threatened to burn him in the fire. This is not an isolated story. Charity begins at home. Those who are cruel at home end up being cruel to the public, Chas V'shalom. And a kind relative ends up spreading kindness. It can sometimes take work to keep reminding yourself that: “He’s my brother”! And this should spread to all the Yidden you know.
This is why Yehuda is Melech, since the Rambam says that the Melech is the Lev (heart) of Klal Yisroel.
