Note in particular his chapter on Metatron and Jesus:
Considering the wide range of traditions in Jewish sources discussing Ezekiel’s vision of a human form on the divine throne, one would expect to find warnings in Jewish texts against confusing this divine manifestation with Jesus. In fact, Yehuda Liebes has brought to our attention the striking identification of Metatron with Jesus in the liturgy and the reverberations of these traditions in passages of the printed edition of The Seventy Names of Metatron and in later kabbalistic works. Liebes argues that the reference to Jesus stems from antiquity and is represented textually as “Yeshua, prince of the countenance,” a clear reference to the angelic Metatron. As Liebes shows through a separate example, these associations and literary traditions stem from Jewish-Christian circles and found their way into canonical Jewish texts.
We can also see the priestly role of Metatron in the article: Priestly and Liturgical Roles of Metatron
The first significant detail of this description is that the tabernacle is placed in the immediate proximity of the Throne, below the Seat of Glory. This tradition does not appear to be peculiar to 3 Enoch’s description since Hekhalot writings depict the Youth, who is often identified there with Metatron, as the one who emerges from beneath the Throne. The proximity of the tabernacle to the Kavod also recalls early Enochic materials, specifically 1 Enoch 14, in which the patriarch’s visitation of the celestial sanctuary is described as his approach to the Kavod. Both traditions (Enochic and Merkabah) appear to stress Enoch-Metatron’s role as the celestial high priest, since he approaches the realm where ordinary creatures, angelic or human, are not allowed to enter. This realm of the immediate presence of the Deity, the Holy of Holies, is situated behind the veil represented by heavenly (dwgrp) or terrestrial (tkrp) curtains.
Another important sacerdotal function mentioned in 3 Enoch 15B and other materials includes the duties of preparation and arrangement of the angelic hosts who participate in the liturgical praise of the Deity. In this respect Metatron is also responsible for the protection of the celestial singers: he guards their ears so that the mighty voice of God would not harm them.
The traditions about Metatron’s liturgical duties inside and near the heavenly tabernacle are not limited to the aforementioned description from Sefer Hekhalot. Thus, one Mandean bowl speaks about Metatron as the one “who serves before the Curtain ()dwgrp).” Alexander proposes that this description “may be linked to the Hekhalot tradition about Metatron as the heavenly High Priest (3 Enoch 15B:1), and certainly alludes to his status as ‘Prince of the Divine Presence.’” Gershom Scholem draws attention to the passage found in Merkabah Shelemah in which the heavenly tabernacle is called the tabernacle of Metatron (Nwr++m Nk#m). In the tradition preserved in Numbers Rabbah 12:12, the heavenly sanctuary again is associated with one of Metatron’s titles and is called the tabernacle of the Youth (r(nh Nk#m):
R. Simon expounded: When the Holy One, blessed be He, told Israel to set up the Tabernacle He intimated to the ministering angels that they also should make a Tabernacle, and when the one below was erected the other was erected on high. The latter was the tabernacle of the youth (r(nh Nk#m) whose name was Metatron, and therein he offers up the souls of the righteous to atone for Israel in the days of their exile.
The intriguing detail in this description of the tabernacle is that it mentions the souls of the righteous offered by Metatron. This reference might allude to the imagery often found in early Enochic materials which refer to the daily sacrifice of the angelic hosts bathing themselves in the river of fire streaming beneath the Throne of Glory, the exact location of the tabernacle of the Youth.
The priestly functions of Metatron were not forgotten in later Jewish mysticism. The materials associated with the Zoharic tradition also attest to Metatron’s duties in the heavenly tabernacle. Zohar II, 159a reads:
We have learned that the Holy One, blessed be He, told Moses all the regulations and the patterns of the Tabernacle, each one with its own prescription, and [Moses] saw Metatron ministering as High Priest within. … he saw Metatron ministering…. The Holy One, blessed be He, said to Moses: Look at the tabernacle, and look at the boy….
The significant detail of this passage from the Zohar is that it refers to Metatron as the High Priest. It should be noted that not only this relatively late composition, but also the earlier materials associated with the Hekhalot tradition, directly identify the exalted angels with the office and the title of the celestial High Priest. Rachel Elior observes that Metatron appears in the Genizah documents as a High Priest who offers sacrifices on the heavenly altar. She calls attention to the important witness of one Cairo Genizah text which explicitly labels Metatron as the High Priest and the chief of the priests:
I adjure you [Metatron], more beloved and dear than all heavenly beings, [Faithful servant] of the God of Israel, the High Priest (lwdg Nhk), chief of [the priest]s (M[ynhkh] #)r), you who poss[ess seven]ty names; and whose name[is like your Master’s] … Great Prince, who is appointed over the great princes, who is the head of all the camps.
As has been already mentioned, Metatron’s service behind the heavenly Curtain, Pargod, recalls the unique function of the earthly high priest, who alone was allowed to enter behind the veil of the terrestrial sanctuary. It was previously explained that the possible background for this unique role of Metatron can be traced to 1 Enoch 14; in this text, the patriarch alone appears in the celestial Holy of Holies while the other angels are barred from the inner house. This depiction also agrees with the Hekhalot evidence according to which only the Youth, videlicet Metatron, is allowed to serve behind the heavenly veil.
It appears that Metatron’s role as the heavenly High Priest is supported in the Hekhalot materials by the motif of the particular sacerdotal duties of the terrestrial protagonist of the Hekhalot literature, Rabbi Ishmael b. Elisha, to whom Metatron serves as an angelus interpres. In view of Enoch-Metatron’s sacerdotal affiliations it is not coincidental that Rabbi Ishmael himself is the tanna who is attested in b. Ber. 7a as a High Priest. Rachel Elior indicates that in Hekhalot Rabbati, this rabbinic authority is portrayed in terms similar to those used in the Talmud, as a priest burning an offering on the altar. Other Hekhalot materials, including 3 Enoch, also often refer to R. Ishmael’s priestly origins. The priestly features of this visionary might not only reflect the heavenly priesthood of Metatron, but also allude to the former priestly duties of the patriarch Enoch known from 1 Enoch and Jubilees, since some scholars observe that “3 Enoch presents a significant parallelism between the ascension of Ishmael and the ascension of Enoch.”
The numbers of Metatron and Shaddai are the same.
From the kabbalahcreationblog:
As it is, the gematria of the letters in both the words (Shadai) and (Metatron) equate. Abraham Abulafia wrote in his Chayei ha-Olam ha-Bah (Life of the Future World), “Thus, ‘our way is his strength’ (Dark-enu Koch-o = 314). Likewise, ‘our strength is his way’ (Koch-enu Dark-o = 314).” This is of course the value of Metatron and Shadai. Abulafia continues: “Behold God’s name Shadai. This is Metatron. He is the ‘Prince of Names’ (Sar HaShemot), who speaks the ‘authority of the Name’ [Reshut HaShem].” Note that the Hebrew terms Sar HaShemot and Reshut HaShem contain the same letters. So the understanding that the power of Shadai is within Metatron, would also mean that every time one invokes this Divine Name for protection, etc., one automatically also calls upon the “Angel of the Divine Presence.”
