출애굽기 3:2의 Kabbalah

Rabbi Yitzchak said, It is written, "The angel of Hashem encamps round about those who fear Him, and he delivers them" (Tehilim 34:8). This verse has already been explained. But in another place, it is written, "For He shall give His angels charge over you," namely, many angels, whereas here only one is mentioned, as it is written, "The angel of Hashem encamps." The verse, "For He shall give His angels charge over you," refers to angels in general, but the verse, "The angel of Hashem," refers to the Shechinah, as it is written, "And the angel of Hashem appeared to him in a flame of fire out of the midst of a bush" (Shemot 3:2). just as it refers to the Shechinah in the first verse, so The angel mentioned here also points to the Shechinah. And so, "the angel of Hashem encamps round about those who fear Him," to encircle them in every direction so as to deliver them. And when the Shechinah resides inside man, all the holy hosts come there.
