Kabbalah su Esodo 14:19

89. There is a Divine name of seventy-two which is comprised of seventy-two three letter units. These are derived from the intertwining of the letters in three Biblical verses (Exodus 14:19 - 21) each of which contains seventy two letters. The first letter of each of the seventy-two units are the letters of the first verse in their natural order. The middle letters of each of the units are the letters of the second verse, backwards, and the last letters, are the letters of the third verse, again in natural order. This name generally indicates the aspect of kindness. In Lurianic Kaballah "The name of seventy-two" usually refers to the extension of Y'H'V'H that has the numerical value of 72-Av (ע"ב) rather than this name.

Know that the first name, which is close to everything created and with which we enter in front of the Blessed King YHVH, and there is no way to see the face of the Blessed King unless it is through this name, the name called Adonay. How so? Know that the specific name YHV"H teaches about the reality of our Blessed Creator and all is dependent on it, but the beginning of the gates and the keys with which we enter to the Name, Blessed Be, is the name called Adonay, and it is the end of all the steps of Hashem, Blessed, from on high to below. And the name Adonay is the basis of the true complete unification, as we still will explain with the help of Hashem, and from there to below is the world of separation. And it is the secret of "And a river goes out from Eden to water the garden, and from there it separates and becomes four heads" (Genesis 2:10). And those are the four camps of the Shechinah, that are under Adonay, Blessed, which is the end of all the steps of unification of the Name from on high to below. This name is called Adonay and it is as a resemblance of a treasury and a treasure store to all types of Flow and all types of Emanations/Causes, all the realities that are found from YHV"H, Blessed, in the way of all the Channels, until 300 deliberated names are found, one opposite to the other; Adonay on high, YHVH in the middle, Ehyeh below. And from there Ehyeh emanates all types of Emanation Flows from the Source which is called Eyn Sof through the way of steps, until it reaches the name YHVH Blessed; and from the name YHVH go all the Channels and the Continuations to the name Adonay. And the name Adonay is the treasury in which all plans of the King are, and it is the Great Provider regarding all what is created in the world, and it is the Feeder and Provider (Siddur Sefarad, Weekday Shacharit, Amidah 81) to all from the force of YHVH that is inside it, according to its mouth those who want to cling to the name YHVH, Blessed, go out and according to its mouth they come in. And there is no [other] way, side or matter to cling to the name YHVH unless it is through Adonay, and therefre this is the name that is the treasure house of the specific name and it is the receiving hall in which YHVH resides. And that is why in the Torah it i always called YHVH with the vocalization Adonay, that is to say , all those seeking YHVH will find through the name Adonay. And since the matter is such, you need to know that Hashem, Blessed, has 54 four-lettered names that are brought by the combination of YHVH, Blessed, and they go to the sum of 216 letters, and those 54 names are the secret of the continuation of the strength in all that is created in the world in the existence of all that is present, and they are the resemblance of the soul regarding 216 letters that are in Vayisa, Vayavo and Vayet [Exodus 14:19-21; the names are made with three letters ABC, where A and C are the first letters and B is 14:20 in reversed order, so the first name is והו, the second ילי and so on. verse 20 is reversed because there is din in it]. And inside those 54 names all the things in the world are included and they are the ones that satisfy all the needs of all existing creatures through Adonay. And if so, it is found that the letters in the name Adonay teach about God's rulership and His matter. How so? א is the secret of Ehyeh which is above; י is the secret of YHV"H which resides in it,ד"נ dalet and nun are the 54 names of existence, which are the secret of all types of flow and emanation and maintenance of all the existing creatures of the world. You've find that you've learned that all rulership and power/distribution is in the hand of Adonay, and that is why it teaches the expression of lordship/authority/mastery, because this name is the master of all the earth with the strength of YHV"H that dwells in it. And since there is not a way for anything alive in this world to come to the Blessed Name unless through its hand, and every petition, supplication and request do not come unless through the hand of Adona"y, they were required to fix at the outset of every prayer "Adona"y open my lips", because that verse is written Alef-Dalet-Nun-Yud and that is the fundamental. And through this name, the prayers enter before YHV"H, Blessed.

Rabbi Elazar said: Even in that time it was the Holy One, blessed be He. Because what is written here, "the angel of Hashem," is analogous to "The angel who redeemed me" (Gen. 48:16) and also to "the angel of Elohim" (Shemot 14:19). For better or for worst, the Holy One, blessed be He, shall always govern this land. For the best - because the land of Yisrael was never passed on to any other supernal governor. And all the other inhabitants of the world should be ashamed of their deeds. For the worst - (Hashem rules in order) to prevent the other ministers from delighting in ruling over it.
