Who is Metatron ?
The origins of the Angel from the third Book of Enoch.
Metatron "the Youth", a title previously used in 3 Enoch, where it appears to mean "servant". It identifies him as the angel that led the people of Israel through the wilderness after their exodus from Egypt (again referring to Exodus 23:21), and describes him as a heavenly priest.
From Hellenistic times, mention of a second divine figure, either beside YHWH or beneath him, occur in a number of Jewish texts, mostly apocryphal.
These Jewish traditions implying a divine dualism were most frequently associated with Enoch. In the rabbinic period they center on 'Metatron', often in the context of debates over the heretical doctrine of 'two powers in heaven' (shtei rashuyot ba-shamayim).
Ultimately these ideas appear to go back to differing interpretations of the heavenly enthronement passages at Exodus 24:10f., Daniel 7:9f. and perhaps even Ezekiel 1:26f.
In 2 Enoch, Enoch is assigned titles commonly used by Metatron such as "the Youth, the Prince of the Presence and the Prince of the World."
In 3 Enoch, Metatron is called the Lesser YHWH.
In Maaseh Merkabah, the text reasons that Metatron is called the Lesser YHWH because in Hebrew gematria, Metatron is numerically equivalent to another name of God Shaddai.
