KETER
References from Jewish Mysticism

The blessed Holy One fashioned for me a majestic robe, in which all kinds of illuminaries were set, and he clothed Me in it. He fashioned for me a Kingly crown in which 49 refulgent stones were placed, and like the sun's orb, and its brilliance shone into the 4 quarters of the heaven of 'Averot, into the 7 heavens, and into the 4 quarters of the world. he set it upon my head and called me "The lesser YHWH" in the presence of the whole Household in the height, as it is written, "My name is in Him." (Ex 23:21) (3 Enoch 12)

Architect's Note : 49 relates to the 49 solar years between Jubilees.

After Metatron tell the heavenly Voyager (and narrator) of "Sefer hekhalot" the tale of his own ascent, he takes his visitor on a tour through the heavens. As they go through the upper realms, the voyager is soon shown a being called Keruviel, who, as the name indicates, is the head of the cherubim in heaven.

Above them is a prince, Noble, Wonderful, Mighty, praised with all manner of praise: Keruviel YHWH is his name, a valiant prince, full of boundless power, a majestic prince, with whom is majesty: a righteous prince, with whom is righteousness; a Holy prince, with whom is holiness; a prince glorified by thousands of hosts, a prince extolled by countless legions.

A crown of holiness in upon his head, with the sacred name engraved upon it, from which lightening flickers.

The bow of the Shekinah is across his shoulders. His sword, like a lightening flash, is on his thigh, his arrows, like lightening flashes, are in his belt, his breastplate of consuming fire hangs around his neck, and coals of Juniper encompass him. The splendour of the shekinah is on his face; His Horns of majesty are on his wheels, a royal turban crowns his head.

The crown on his head is radiant like the Throne of Glory, and the height of the crown is a journey of 502 years.(measures) There is no other kind of radiance, no other kind of splendour, no other kind of brilliance, no other kind of light in the world that is not placed in that crown.

Serefiel is the name of that prince, and the name on his head is "Prince of Peace."

Architect's Note : I consider these 4 angelic names to be of the same angelomophic size as they all wear the crown, in contrast to those who carry the Throne, of which the crown is made up.
