In my Dvar Torah about Dovid and hands I made a typo. This is how it should end.
Memeilah, Zerach stook out his hand. He wanted Dovid to come from him! But his hand was pulled back and Peretz broke forth! So Dovid descended from him!
I will add another Dvar Torah that expands on the theme of areivus.
I mentioned how Yehuda’s areivus for Binyamin was a wonderful thing to repair the hatred between the sons of Leah and Rachel, and that klal Yisrael are areivim ze la ze. In areivus we don’t overide each other, but work together in peace and friendship.
In halacha there are three eiruvs, and they are also about promoting peace and frienship. An eiruv techumin allows you to go to someones kidush or bris (that live far away) and promotes peace and friendship among people. The eiruv chateiros allows you to carry in your neighborhood and promotes peace and friendship among neighbors. The eiruv tavshilin lets you cook on Yom Tov for Shabbos and promotes peace and frienship between husband and wife.
Here is the amazing part. ??????? is the mesechta in shas that discusses eiruv techumin and eiruv chateiros. ??????? spelled backwards is ??? ???, which alludes to peace and friendship. ??? alludes to the pasuk ???? ??? ????? ???? ???? ????? ??????. So ??? is peace, and a ?? (Raya) is a friend. So ??? ??? is peace and friendship.
