YHWH

Gershom Scholem, "In Jewish Mysticism," in On the Kabbalah and Its Symbolism:

[The] basic idea of the Torah as the Name of God was the source of certain other Kabbalistic developments. It goes without saying that such an assertion about the Torah does not refer to the document written in ink on a scroll of parchment, but to the Torah as a pre-existential being, which preceded everything else in the world....
One of the most important variants of this theory occurs in Joseph Gikatila, a leading Spanish Kabbalist who wrote at the end of the thirteenth century... In his view, the Torah is not itself the name of God but the explication of the Name of God. To him the Name meant exactly what it had meant for the Jewish tradition, namely the tetragrammaton, which is the one and only true name of God. He writes: "Know that the entire Torah is, as it were, an explication, and commentary on, the tetragrammaton YHWH."

Later, in the same essay, Scholem quotes Pinhas of Koretz:

Indeed it is true that the holy Torah was originally created as an incoherent jumble of letters. In other words, all the letters of the Torah, from the beginning of Genesis to the end of Deuteronomy, were not yet combined to form the words we now read, such as "In the beginning God created" or "Go from thy land," and so on. These words, on the contrary, were not yet present, for the events of Creation that they record had not yet taken place. Thus all the letters of the Torah were indeed jumbled, and only when a certain event occurred in the world did the letters combine to form the words in which the event is related.... As soon as something happened, the corresponding combination of letters came into being. If another event had occurred in its place, other combinations of letters would have arisen....
