The Holy One, blessed be He, is called Adonai

549. Rabbi Yehuda said, Adonai, WHEN WRITTEN OUT FULLY, IS SPELLED Aleph Lamed Pe, Dalet Lamed Tav, Nun Vav Nun, Yud Vav Dalet, is called 'the Holy One, blessed be He,' DENOTING ZEIR ANPIN, NOT YUD HEI VAV HEI, AS IT IS WRITTEN. That which is pronounced as written IS CALLED 'ADONAI.' Who is it? Rabbi Yosi said, It refers to "visions of Elohim," MEANING MALCHUT, CALLED 'VISION.' HE ASKS, Why is it written visions in the plural? HE ANSWERS, IT INCLUDES ALSO the entirely of all, Yud Vav Dalet, Hei Aleph, Vav Aleph Vav, Hei Aleph, DENOTING ZEIR ANPIN. He asks, Visions of what? OF THE NAME YUD HEI VAV HEI, OR THE NAME ADONAI? HE ANSWERS, Aleph Lamed Pe, Dalet Lamed Tav, Nun Vav Nun, Yud Vav Dalet, AS BOTH ARE THUS PRONOUNCED. The one, MALCHUT, is pronounced as written, while the other, ZEIR ANPIN, is not pronounced as it is written, WITH THE NAME YUD HEI VAV HEI BUT PRONOUNCED AS THIS NAME ADONAI. And so it is written "visions of Elohim," IN THE PLURAL, FOR IT INCLUDES ZEIR ANPIN AND MALCHUT. FOR THIS REASON, BOTH ARE CALLED BY THE NAME 'ADON ('MASTER').' THIS IS THE REASON FOR THE WORDS OF RABBI YITZCHAK.

550. Rabbi Yehuda ALSO said, Sometimes the celestial are called with terms of the lower, and sometimes the lower are called by names of the celestial. And so it WRITES "the master, Hashem" with a supernal name, ZEIR ANPIN which is Adonai, WHICH IS A LOWER NAME, MALCHUT. In many ways are the words clarified. Blessed is the Merciful One, blessed is His name forever and ever.
