Aleph – Tav the letters of the Aleph-Bet
Rabbi Dov Ber, the Maggid of Mezritch
“It is known in Kabbalistic literature that the letters of the Aleph-Beis were created first of all. Thereafter, by use of the letters, the Holy One, Blessed is He, created all the worlds. This is the hidden meaning of the first phrase in the Torah, “In the beginning God created אֵת ” –that is, God’s first act was to create the letters from א to ת.
Leviticus 26 verse 3 begins with Alef, verse 13 ends with Tav which indicates that the commandments are as perfect as the universe in which they are to be fulfilled.
The sum total of human knowledge derives from the Torah because the universe is a product of torah which is the blueprint of the world, as the Midrash teaches: God looking into the Torah and created the world (Zohar, Ruth 88) When His Ineffable Word took physical form, heaven and earth became the clothing for the word of God which infuses Creation, and without which Creation would not continue to exist. The spiritual Torah which preceded the world became clothed in ink and parchment, and the Godly wisdom which is the essence of Torah remained hidden in its words and letters (Ramban)
With the advent of Creation, the wisdom of God took the form of the 613 commandments. But the precepts are not isolated phenomena; they are all interrelated aspects of a single Torah, like the organs and vessels of a single human body to which the totality of the commandments are likened. Indeed, the 613 commandments give spiritual life and nourishment to the organs and vessels of the individual human being just as they provide continued existence to all of Creation.
