Angel Michael is on the Right, Chessed. He holds to and serve the name אדני ADNY, more than other angels.
Michael is attached to the Shechina and brings the aspect of the name ‘אלהים’,‘ELHYM’ that supports Malchut and the name אדני. This name comes through Yessod and without the angel Michael, the support is removed, including the support of the name שדי, ‘Shadai’ that is God’s name at the level of Yessod.
Abraham served food to the three angels that came to deliver message from God that Sarah would carry and deliver a child.
Angels don’t eat food of this world. They are made out of fire and the food that Abraham served them was consumed by this fire that was concealed in the air.
Abraham was very pleased with his guests.
The three angels that came to Abraham were;
Michael – to deliver the message that Sarah will have a child.
Raphael – to heal Abraham from the circumcision.
Gabriel – to destroy Sodom
Michael left with the Shechina as it says;
“וַיְכַל לְדַבֵּר אִתּוֹ וַיַּעַל אֱלֹהִים מֵעַל אַבְרָהָם”
“And He finished talking with him, and God (ELHYM) went up from Abraham.”
Shortly after the two remaining angels went to Sodom to rescue Lot and destroy the wicked city.
“וַיָּבֹאוּ שְׁנֵי הַמַּלְאָכִים סְדֹמָה בָּעֶרֶב וְלוֹט יֹשֵׁב בְּשַׁעַר סְדֹם וַיַּרְא לוֹט וַיָּקָם לִקְרָאתָם וַיִּשְׁתַּחוּ אַפַּיִם אָרְצָה”
“The two angels came to Sodom in the evening, and Lot was sitting in the gate of Sodom. When Lot saw them, he rose to meet them and bowed himself with his face to the earth”
