"God spoke to Moses and said to him, 'I am YHVH. I revealed Myself to Abraham, Isaac and Jacob as God Almighty (El Shaddai), and did not allow them to know Me by My name YHVH.”
The forefathers, Abraham, Isaac, and Jacob, originate spiritually from Supernal Mother, Ima Ilaa, which is the name of God with the gematria of 63 (יוד הי ואו הי). The three letters yud (ייי) found in this name are the three forefathers.
The first letters of their names, together with another name of Jacob - Israel are alef, yud, yud, yud, with the gematria of 31 (אל). That is the name “El,” and it explains the meaning of “I revealed myself as El.” Abraham, who is the first, is thus called “Chesed El” - the Kindness of God.
It is also known that the Supernal Mother is crying on her chair, and there her name is “El Shaddai” - “God Who has it in His power to fullfill His promise,” but this appearance to Abraham was only by way of substitution, in a vision, “bamachaze” - which is in Aramaic, and not Hebrew, that is, a substitution.
The last letters of the names of the forefathers, M, K, B, are SH, D, Y (Shaddai) but also by way of substitution, in the alphabet called “At-Bash”, where the first letter of the alphabet is substituted with the last one, and so on.
The gematria of the name Moses (Moshe - 345) himself is also El Shaddai - 345, but without substitutions, in the revealed manner. Moses encompassed all the powers of the forefathers. However, he also had an added name “Mah”, with the gematria of 45 (יוד הא ואו הא), when he said, “And we, what (mah) are we?” That was what he added over the forefathers, making him the greatest of the prophets.
