Angels-Hadraniel

Hadraniel (or Hadarniel, among other variant spellings), meaning
“majesty [or greatness] of God,” is an angel assigned as gatekeeper at
the second gate in heaven. He is supposed to be more than sixty myriads
of parasangs (approximately 2.1 million miles) tall and a daunting
figure to face.
When Moses arrived in heaven to get the Torah from God, it was
said that he was speechless with awe at the sight of Hadraniel. Hadraniel
didn’t think that Moses should have the Torah, and made him
weep in fear, which caused God to appear and reprimand Hadraniel
for causing problems. Hadraniel quickly decided to behave and acted
as a guide for Moses. This was a great help, because (according to
Zoharic legend) “when Hadraniel proclaims the will of the lord, his
voice penetrates through 200,000 firmaments.” Also, according to the
Revelation of Moses, “with every word from his (Hadraniel’s) mouth
go forth 12,000 flashes of lightning.”
In Gnosticism Hadraniel is only one of seven subordinates to
Jehuel, prince of fire (King, p. 15). In the Zohar I (55b), Hadraniel
speaks to Adam about Adam’s possession of the Book of the Angel
Raziel, which was said to contain secret information that not even the
angels knew.
