קבלה אויף בראשית 17:2

Now that you have been informed of this, know that HaShem-יהו"ה wanted to perfect our forefather Avraham in all the Sefirot and told him,¹³⁵Genesis 17:1 “Walk before Me and be perfect.” That is, “In order for you to be connected to My chariot, I am placing an imprint in your flesh which is called, “the covenant of the flesh-Brit Bassar-ברית בשר,” as it states,¹³⁶Genesis 17:2 “I will place My covenant-Brit-ברית between Me and you.” It further states,¹³⁷Genesis 17:13 “Those born in your household or acquired must be circumcised; My covenant shall be in your flesh as an eternal covenant.” The words, “My covenant shall be in your flesh” refer to “the covenant of flesh-Brit Bassar-ברית בשר,” and the words, “as an eternal covenant” refer to the covenant of the tongue-Brit HaLashon-ברית הלשון, which is the matter of Torah, which is drawn from the Sefirah of Understanding-Binah-בינה and is the matter of counting fifty days (Sefirat HaOmer) to the giving of the Torah, corresponding to the counting of fifty years to the Jubilee-Yovel-יובל. That is, had Israel not accepted the covenant of the flesh-Brit Bassar-ברית בשר, they would never have merited receiving the Torah, which is the covenant of the tongue-Brit HaLashon-ברית הלשון. This is why Sefer Yetzirah states,¹³⁸Ending paragraph of Sefer Yetzirah. “When our forefather Avraham came, saw, investigated, understood, engraved, thought, and succeeded, the Lord of the world-Adon HaOlam-אדון העולם revealed Himself to him and called him,¹³⁹Isaiah 41:8 ‘My Beloved.’ He made a covenant with him between the ten fingers of his hands, which is the covenant of the tongue-Brit HaLashon-ברית הלשון and between the ten toes of his feet, which is the covenant of circumcision-Brit Milah-ברית מילה.” And if you say that Avraham was not given the matter of Pri’ah-פריעה,¹⁴⁰As stated in Talmud Bavli, Yevamot 71b the matter of Pri’ah-פריעה was first given in the generation of Joshua. which corresponds to HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י, know that actually, this quality was already his, for he was the first one to call HaShem-יהו"ה by this title.
