Kabbalah sa Deuteronomio 5:5: Sha'arei Orah

Now, in many places this Sefirah is called Understanding-Binah-בינה. The reason is because it is the secret of the Upper Interpreter-HaMeilitz HaElyon-המליץ העליון positioned between the upper Sefirot and the lower Sefirot, who emanates beneficence and blessing to the other Sefirot from the Supernal Crown-Keter Elyon. Through this Sefirah man contemplates the Primary Root of all roots, and the Foundation of all foundations.¹⁵²Mishneh Torah, Hilchot Yesodei HaTorah 1:1 – That is, the knowledge of the Singular Preexistent Intrinsic and Essential Being HaShem-יהו״ה, blessed is He. For, without Understanding-Binah, there is no way to enter the knowledge of HaShem’s-יהו"ה Singular Preexistent Intrinsic and Essential Being, blessed is He. It therefore is compared to a Trusted Interpreter (Meilitz HaNe’eman),¹⁵³Like Moshe, about whom it states (Numbers 12:7), “He is trusted-Ne’eman-נאמן throughout My house,” and is called the Faithful Shepherd-Ra’ayah Mehemna or the Shepherd of Faith, as mentioned in the Fifth Gate, and as will be hinted in the next verse and mentioned shortly. as Moshe stated,¹⁵⁴Deuteronomy 5:5 “I stand between (Bein-בין)¹⁵⁵The word “between-Bein-בין” also means “understand-Been-בין” and shares the same root as Understanding-Binah-בינה. That is, the quality of Understanding-Binah is positioned between the upper Sefirot and the lower Sefirot, and there is no path to attain the upper Sefirot except by way of Understanding-Binah-בינה which is positioned between-Bein-בין them.

HaShem-יהו״ה and you.”
