The Blessing of the Moed - When Did Hashem Say He Would Bless Us?

Okay, I got to my Eid. We say every day in the davening, "V'as ye'aneinu Hashem Elokeinu es birkas my'adecha." We ask Hashem to bestow upon us the blessing of the my'eid l'chaim, ul'shalom, ul'simcha, ul'sason. And then we say, "Ka'asher sisah v'amarta l'varecheinu." Like you wanted and you said you're going to bless us. When did Hashem say he was going to bless us? What What is this reference? "Bless us like you said you're going to bless us." Where in the Torah did Hashem commit commit to give a bracha to Klal Yisrael on the Yamim Tovim? So, the Brisker Rav says, "This is referring to the pasuk, "V'hayisa ach samei'ach." The end of Parshas Re'eh, perek tet-zayin, pasuk tet-vav, "Ki y'varechecha Hashem Elokecha b'chol t'vu'asecha v'chol u'v'chol ma'aseh yadecha v'hayisa ach samei'ach." Rashi says, "The words v'hayisa ach samei'ach is not a command. L'fi p'shuto it's simply the ain zeh lashon tzivui. This is not an expression of command ela lashon haftacha. It's a promise. This is a bracha." So, says the Brisker Rav, "When we say, 'Ribbono shel Olam, give us the blessing of your my'eid, ka'asher sisah v'amarta l'varecheinu,' like you said you were going to bless us, it's referring to the pasuk v'hayisa ach samei'ach." But interestingly, in the Sefer Otzar HaTefilos, in the Perish Tikun Tefilah, he offers a completely different interpretation. What does it mean v'amarta l'varecheinu? He says, "In Devarim, perek tet-zayin, pasuk yud, the pasuk says, "Ka'asher y'varechecha Hashem Elokecha." That's the first bracha. Perek tet-zayin, pasuk yud, "Ka'asher y'varechecha Hashem Elokecha" in reference to the Yom Tov of Shavuos. And then perek tet-zayin, pasuk tet-vav, in the reference to Sukkot the pasuk says "Ki y'varechecha" and then at the end of all the yamim tovim it says "Ish kamat nasyado k'vir Hashem Elokecha asher nasah lach" three times it says the bracha of the moed. Then the Tikun Tefillah adds also in Parshas Ki Tisa Perek Lamed Daled Pasuk Kaf Gimel "Shalosh p'amim bashanah yera'eh kol z'churecha" three times a year you're going to go up to Yerushalayim and "Ki oreesh mipanecha" when I drive out the nations "v'rachavti es g'vulecha" and I expand your borders and when you go up to Yerushalayim don't worry that the nations of the world are going to covet and desire land and conquer your land "v'lo yachmod ish es artzecha" that no man will covet your land says the Tikun Tefillah this is the bracha that we reference when we say "Vi'amarta l'varchinu" that when we're oleh regel it will not have a detrimental effect on our assets and on our homes and on our real estate. Perhaps in our times then if when we say even in our times "Ka'asher rotzisa d'amarta l'varchinu" that refers to there's a special blessing that Hakadosh Baruchu gives us on the moed then nothing we do to honor Hashem on the moed will be will cause us any kind of loss or any kind of detriment but ad rabah it will be a source of great bracha so it comes out four times in the Torah according to the Tikun Tefillah Hashem blesses the Jewish people specifically on the moed. Wishing everyone a gutten moed.
