What are the seventy-two letters, and how can they be used?

Hello

The explicit, most awe-inspiring of all the divine names has a combination of seventy-two names, each consisting of three letters, and all the names together form the name of the attribute of kindness of Hashem in His world. These names are formed from three verses in the Torah, in the Book of Exodus [chapter 14, verses 19-21], in each of which there are 72 letters. In my opinion, the intention behind these names is a matter for great kabbalists of the first rank, who have already delved deeply into the wisdom of the hidden Torah for many years, and anyone who deals with this without being worthy of it endangers his soul, may Hashem protect us.

According to some early authorities, this is the name that the High Priest mentioned on Yom Kippur at the time of the confession, and then all the people would kneel with their faces to the ground, because of the great preciousness of this name, and from this one can understand the fear surrounding this name. If you still want to connect with these names, it would be best for you to recite the three verses exactly as they are written in the Torah, and I am copying them here:

 (יט) וַיִּסַּע מַלְאַךְ הָאֱלֹהִים הַהֹלֵךְ לִפְנֵי מַחֲנֵה יִשְׂרָאֵל וַיֵּלֶךְ מֵאַחֲרֵיהֶם וַיִּסַּע עַמּוּד הֶעָנָן מִפְּנֵיהֶם וַיַּעֲמֹד מֵאַחֲרֵיהֶם:

 (כ) וַיָּבֹא בֵּין מַחֲנֵה מִצְרַיִם וּבֵין מַחֲנֵה יִשְׂרָאֵל וַיְהִי הֶעָנָן וְהַחֹשֶׁךְ וַיָּאֶר אֶת הַלָּיְלָה וְלֹא קָרַב זֶה אֶל זֶה כָּל הַלָּיְלָה: 

(כא) וַיֵּט מֹשֶׁה אֶת יָדוֹ עַל הַיָּם וַיּוֹלֶךְ יְה-וָה אֶת הַיָּם בְּרוּחַ קָדִים עַזָּה כָּל הַלַּיְלָה וַיָּשֶׂם אֶת הַיָּם לֶחָרָבָה וַיִּבָּקְעוּ הַמָּיִם:

And afterward say, May it be the will before Hashem that by the power of the names combined from the verses I said He will bestow upon me from the treasury of His kindness, etc., etc., and continue to ask for whatever you wish.
